Though historical records date the history of the Chamba region to the Kolian
tribes in the 2nd century BC, the area was formally ruled by the Maru dynasty,
starting with the Raju Maru from around 500 AD, ruling from the ancient
capital of Bharmour, which is located 75 kilometres (47 mi) from the town of
Chamba. In 920, Raja Sahil Varman (or Raja Sahil Verma) shifted the capital of
the kingdom to Chamba, following the specific request of his daughter
Champavati (Chamba was named after her). From the time of Raju Maru, 67
Rajas of this dynasty have ruled over Chamba until it finally merged with the
Indian Union in April 1948.

3) PHYSIOGRAPHY:
3.1 General
The Chamba district in the present form came in to existence on 1st November
1966 which is bounded on north-west by Jammu and Kashmir, on the north-east
and east by Ladakh area of Jammu and Kashmir state and Lahaul and Bara-
Bangal area of Himachal Pradesh, on the south-east and south by the District
Kangra of Himachal Pradesh and Gurdaspur District of Punjab. The district is
Situated between north latitude 32° 11΄ 30″ and 33° 13΄ 06″, and east longitude
75° 49΄ 00” and 77° 03΄ 30″ . The area of the district is 6,522 sq. km with
Chamba as its Headquarters. There are 1591 villages in the district. The district
has been divided into7 Sub-divisions [Chamba,Churah, Pangi, Bharmaur,
Dalhousie, Salooni,Chowari].

The district has varying altitude ranging from 609 to 6402 m above mean sea
level, with some plain areas touching Pathankot district of Punjab in the south
and Kangra district of H.P. in the South. In the East it touches Lahal Spiti
district, in North with Jammu and Kashmir. The Ravi is the main river of
Chamba district and is the heart and soul of the Chambyals. With its tributaries,
it drains the whole of Chamba valley proper between Dhauladhar and Pangi
range and thus commands the largest and most important part of the district.
The river originates from Bara Bangahal area of Dhauladhar. The Main
tributaries of Ravi are Budhil, Tundah, Beljedi, Sal, Siul, Siowa The river
Chenab or Chandrabhaga rises from the mountains of Baralacha pass by two
heads, the stream with its source on south-eastern side of the pass being called
the Chandra and the other one which rises from north-western side is called the
Bhaga. After the confluence of these two sister streams at Tandi, the river is
generally known as Chenab. There are no large-sized lakes in Chamba district.
However, a few water bodies namely Khajjiar Lake. The district with respect to
revenue control has been divided into seven Tehsils and three sub-Tehsils.
There are 283 Gram Panchayats.

In Chamba District, there are several small and deep valleys spread in
different parts with moderate to high elevations. Here the cultivation is possible
only in small terrace, flood plain and the area is moderate to gentle sloping
and also holdings the area in either in the river basin or high hilly area etc. In
valley area the cultivation is mainly spread over large area. Area with high
altitude is best for the growing orchards like’s apples and other fruits such as
almonds, Walnuts etc. Maximum area/ land are under the dense and thick forest
cover and orchards. The main forests varieties are deodar, Chil, Pine, kail .Rai,
ban etc and suitable altitude for the growth of this type of vegetation is 1600-
1800m.

of the people considerably. The climatic condition prevailing in Himachal
Pradesh and varying elevations are most suitable for the growth of forests.
In Chamba District, various important species of trees namely Deodar, Kail,
Chil, Oak, Mohru and Kharu etc. are found in the forests and the major forests
produce are resin and medicinal herbs. The available resin in the District is
being processed by two resin and turpentine factories at Bilaspur and Nahan.
However, the medicinal herbs are being exported in raw from out of the District.
The forests in the District are mainly in the tract of
outer Shiwalik to the mid Himalayas. The soil is generally sandy-loom and
depth is shallow except in the areas having vegetation cover where it is fairly
deep in the region above 1500 Mtrs. The soil is generally deep and contains a
thin layer of leaf moulded species of Ban, Oak, Chil, Kail and Deodar. In the
lower elevation scrub forms are found while in the higher altitude Deodar, Kail
etc. are available, hi the lower ranges with warmer aspects and sharp slopes with
deep soil and favourable conditions, species of mixed forest of Bamboo and
scrub are found.

limestone of cement grade within the Lower Himalayan Zone. In addition it has
sizeable reserve of chemical grade limestone. Dolomite occurs extensively and
can find application in metallurgical industries. The Shali, the Deoban and the
Larji are the principal Mesoproterozoic carbonate belts of great potential. The
other belts with carbonate lithounits are Meso to Neoproterozoic Mandhali, the
Basantpur-Kunihar, the Krol and the Jutogh. In the Higher Himalayan sector of
Lahaul-Spiti and Kinnaur, the Early Carboniferous Lipak Formation and the
Triassic-Early Jurassic Lilang Group are the important carbonate belts. The
Early Carboniferous Kalhel limestone of Chamba is also a good source. The
Palaeocene-Eocene Kakara and Subathu Formations contain significant
proportion of carbonate rocks.

13 GEOLOGY:-
Geologically, Himachal Pradesh can be broadly divided into two major geo-
technic zones viz. the Lesser Himalaya tectogen in the south and the Tethys
Himalayan Tectogen in north. These two tectonic zones are juxtaposed with
each other along a major tectonic break collectively designated as Main Central
Thrust in the sense defined by Srikantia(1988).. The oldest rocks are of
undifferentiated Proterozoic age, comprising carbonaceous phyllite, schist,
gneiss, quartzite and marble. The Ghoghar dhar (undiffertiated Proterozoic
age) occurs as an intrusive body within the Chail Group minor aplite and basic
veinlets. The Sundernagar group of rocks of Meso-Proterozoic age is
represented by quartzite with basic flows. The Shali group of (Meso-
Proterozoic) comprising Limestone, dolomite, slate & quartzite. The Subathu
consist mainly, of olive green shales and Grey shales. At the top, a band of
white quartzite exposed; this band of white quartzite has been taken as the
marker, defining the top of the Subathu sequence. The thick sequences of
brackish and fresh water sediments immediately succeeding the fossiliferous
marine Subathu are classified as Dharamshala formation. The Dharamshala
formations are widely exposed, in the Mandi parautochthon, further west in the
autochthon, these rocks are exposed, in the core of the Sarkaghat anticline. The
Shiwalik group of Middle Miocene of Early Pleistocene age comprises coarse
clastic fluviatile deposits of sandstone, clay and conglomerates. The Quaternary
sediments( older Alluvium and Newer Alluvium) along prominent channels
consisting of sand, silt clay, pebbles and cobbles occurring along present
channels of Middle to late Pleistocene and Holocene age.

6. Water supply & irrigation Scheme
7. Any other physical features of public importance etc.
Also, these following are the important guiding principles considered while
recommending the river/stream bed or part of river/ stream bed for collection
for minor minerals:-
1.The production of aggregate in a particular area is a function of the
availability of natural resources, the size of population, the economy of the area
and various development and infrastructural works being undertaken in the area
like road construction, hydro-electric projects etc. Further, being a low-value,
high- volume mineral commodity, he prices are dramatically affected by
transportation distances. If the distances increases, the transportations cost may
increase much more than the cost of the aggregates
2.A stable river is able to consistently transport the flow of sediments produced
by watershed such that its dimensions (width7 depth) pattern and vertical profile
are maintained without aggrading (building up) or degrading (scouring).
3.The amount of the boulders, cobbles pebbles and sand deposited in riverbed
24
equals to the amount delivered to the river from watershed and from bank
4.It is compulsive nature for the river to meander in their belts and therefore
they will have to be provided with adequate corridor for meandering without let
or hindrance. Any attempt to diminish the width of this corridor (floodway) and
5.Erosion and deposition is law of nature. The river/stream has to complete its
10. The ratio between the width of meander belt and width of the stream

Fig:- 5:
Mainly three types of minor mineral constituents such as sand, stone and bajri
are required for any type of construction apart from other material like cement
and steel. In earlier times, the houses/ buildings were constructed in form of
small dwellings with walls made up of mud plaster, stone and interlocking
provided with wooden frames and there were negligible commercial as well as
developmental activities resulting in less demand of building material. However
with the passage of time, new vistas of developmental activities were started. As
such the demand of minor minerals in the District started an increasing trend
due to construction of Hydro projects. In order to meet the requirement of raw
material for construction, the extraction of sand, stone and bajri is being carried
26
out exclusively from the river beds. The demand of sand is mainly met through
by river borne sand whereas the demand of bajri/grit is either met through river
borne collection or through manufactured grit by stone crushers. The demand of
dressed or undressed stone is met through the broken rock material from the hill
slope.
The local residents used to lift gravel etc. from the river beds to meet out their
bonafide requirement, however after coming into being the Himachal Pradesh
Minor Minerals (Concession) and Minerals (Prevention of Illegal Mining,
Transportation and Storage) Rules, 2015, the mining is regulated in accordace
with the rules.
At present about 5 Nos of mining leases have been granted/executed under the
ibid rules in the different parts of the District and the detail are tabulated
below:-

Mainly three types of minor mineral constituents such as sand stone and bajri
are the main constituents required for the moderen construction/developmental
activities apart from other material like cement and steel.As such the demand of
minor mineral in the District started an increasing trend. In order to meet the
requirement of raw material for construction, the extraction of sand, stone and
bajri is being carried out exclusively from the river beds.
The increase could be gauged from the fact that during 2011-12 the royalty
receipt on minor mineral was merely 58,94,528 l which has now been increased
to 1,76,07,318 . The royalty received since 2011-12 onwards is tabulated in the

etc. Based on this, Survey, the Mining Officer shall put up the proposal for
auction of River/Stream/Khalla beds to the following Sub-Divisional
Committee for its approval
Only after the recommendations of this committee, the area shall be put to
public auction.
The process of identification of site and auction of river beds is under process
and some Constraints with regard to auction of miner mineral.
In the Year 1952 Forest Department issued two notifications under the provision
of Section 29 of Indian Forest Act (XVI of 1967) as applied to Himachal
Pradesh. These notifications were:-
The Hon’ble Supreme Court of India in its oders dated 12/12/89 issued interim
directions in the writ petition No 202 of 1995 titled as T.N. Godaverman
Tirumulkpad versus Union of India and others. Apart from other directions it
directed that all the ongoing activity within any forest in any State through out
the country without prior approval of Central Government must cease forthwith.
With the applicability of Forest Department, notification dated 25/2/1952 and
15/1/1952, wherein all the waste land in the ownership of Govt. has been
declared as forest land and thus attracted the provision of FCA, 1980. The
Department of Industries which has the mendate to regulate the provision of
Mines and Minerlas (Development & Regulation) Act, 1957 and Rules framed
32
there under is unable to auction the minor mineral quarries in various parts of
the Himachal Pradesh.
18.1. EROSION:
Stream erosion is the detachment of material from the bed or sides of the
channel. Approximately 95% of a stream's energy is used to overcome frictional
effects imposed by the channel and internal molecular friction. This leaves only
5% of the stream's energy for vertical and lateral cutting. Flowing water erodes
in three ways. First, flowing water dissolves materials from the channel
contributing to stream's dissolve or, Solution load. Secondly, the impact of
water, or Hydraulic action on the sides and bed of the channel dislodges
materials and makes them available for transport as part of the stream load.
Materials too heavy to suspend, scoot and roll across the bed, eroding the
channel by Abrasion as a river winds its way from its source to its mouth. A
number of processes of erosion take place such as:
1. Corrosion – This is the wearing away of the river channel by water + load
(load = material carried in the river e.g. boulders, pebbles, sand etc)
2. Attrition – As the load is carried by the river, bits collide and these are
further broken up.
3. Solution – This is where certain rocks (e.g. limestone) are dissolved by the
river.
18.2 TRANSPORTATION:
A river moves its load by :-
(1) - Rolling large stones and boulders. (Stream load).
(2) - Carrying sand, mud and silt in suspension. (Suspended load).
(3) - Carrying minerals in solution. (Solution).
33
Transportation is the movement of earth material, by water. The material
transported through the stream is it's stream load. Stream load is composed of
dissolved or solution load, suspended load, and bed load. The dissolved load
comes primarily from ground water seepage into the stream. Suspended load is
comprised of sediment suspended and transported through the stream. Turbulent
flow suspends clay and silt in the stream. Suspended load comes from material
eroded from the surface bordering the channel and deposited in the stream, as
well as, erosion of the channel itself.
The stream capacity is the maximum load of sediment a stream can carry for a
given discharge. As one might expect, stream capacity increases with increasing
flow velocity. Increased water velocity imparts a greater frictional drag on bed
to erode it. Turbulent flow occurs under higher velocity, thus increasing the
water's ability to dislodge material from the bed or sides of the stream. Stream
competence is the largest size material, the stream can move under a given
discharge.
Bed load is that which is moved across the bed of the channel. Bed load is
transported in two ways, traction, which is a scooting and rolling of particles
along the bed. The second is saltation, a bouncing-like movement. Saltation
occurs when particles are suspended in the stream for a short distance after
which they fall to the bed, dislodging particles from the bed. The dislodged
particles move downstream a short distance where they fall to the bed, again
dislodging particles upon impact.
34
• The river channel is small, narrow and rough and usually shallow.
• The stones and rocks increase wetted perimeter.
• The volume of water is low as there are very few tributaries flowing into it.
Features such as:-
Interlocking Spurs, Pot holes and water falls or Gorges are developed in the
upper course of a stream.
Interlocking Spurs:
Interlocking spurs are alternate hills in the river valley. The river does not have
a high water volume at this point and even though it is fast flowing, the river
cannot laterally erode (sideways) to remove the spurs. Because of this, the river
has to flow around the spurs, eroding vertically.
Potholes:
As the river is vertically eroding in the Upper Course, potholes are created when
larger pieces of load that the river cannot remove by traction are twisted around
by eddy currents. The river is not strong enough here to pull the large boulder,
and the obstruction creates a swirling motion in the water. Eventually, the
boulder creates a pothole, by abrasion on the river-bed.
In the Upper Course, the river is not only eroding vertically (down) but towards
its source The river erodes the softer rock underneath the harder rock on top
faster, and this means the level of the land along the river's course becomes
lower over time and the waterfall retreats back towards the source.
Meanders:
In the middle course, the amount of water and material in the river increases as
more tributaries join in. The bed widens, its slope becomes gentler, and the
water flows much more slowly as the river flows out of the mountains. As a
slow-moving river cannot keep heavy material moving, piles of gravel form
along the banks. At this stage, the river carries its load of sand, mud, and small
stones suspended in water. It also begins to swing from side to side, cutting into
some banks and drifting away from others. As there are no obstacles such as
rapids, the river's course becomes smoother and more regular.A floodplain is a
wide and flat plain. It is built up by alluvium laid down on the river banks
during repeated flooding.When there is a flood, the river overflows its banks.
When the flood subsides, there is a decrease in the volume of water and the
river starts to deposit its load. Most of the alluvium is deposited on the banks
35
close to the river. With repeated flooding, the materials that are deposited on the
river banks accumulate to form floodplains.The path of the middle river is
always changing as it cuts sideways into the land and starts to deposit its load.
Loops, called meanders and oxbow lakes are typical features of this part of the
river. During a storm, meanders stop river water flowing easily. This cause
water to build up in places, and may lead to flooding
(c) Lower Course:
In the lower course:
• The river channel is the widest and the deepest.
• It has the largest volume of water and load because of the numerous tributaries
flowing into it.
• There is lateral erosion along this course.
Features such as
Leves, Braided Channels, Deltas and oxbow lake are developed in the upper
course of a stream.
Levees
In the monsoon, when the river volume is at its highest, the river is prone to
flooding. As the river overflows its banks, friction with the floodplain slows
down the flow. The loss of energy means load is deposited. The deposition is
graded - this means that the larger particles are dropped first (being the heaviest)
near the river bank edge and the smaller particles are taken further along the
floodplain. The larger particles build up over repeated floodings to create a
leveé, which increases the capacity of the river.
However, after Monsoon when the river volume and energy is at its lowest,
deposition occurs in the river channel, raising the bed. This means that the
capacity of the river is lowered and flooding again will occur in the monsoon
months, creating bigger leveés. This cycle raises the river higher than the
landscape over time.
Drainage:
The entire area possesses dendritic to sub-dendritic type of the drainage pattern
with formation of small gullies. The Ravi River generally flows in westerly
direction.

To traversed the different locations along the Ravi river, Sal & Suil River and
also along and its tributaries and catchment area. During visit to Chamba
district, different traverses were taken to identify the mineable deposits in the
catchment of above mentioned rivers.
The following are promising sites identified for collection/extraction of sand,
stone and bajri from the all rivers and its tributaries flowing through the District
Chamba:
A. Ravi River:-
1. Holi Deposit;-
This deposit is located about 300-400 metres downstream from Holi station on
left bank. It comprises of rock fragment of small size mainly of slate, phyllite &
sand and stone etc. This deposit is considerable for lifting of materials. There
will be no possibility of degradation of environment in case this material is
lifted from this site and pit out area after excavation will be replenished in rainy
seasons for considerable thickness. Hence the site is recommended to put for
auction.
2. Bagga-River deposit;-
3. Bakanipul to Kalsuin:-
37
is also recommended for auction as it will not cause any adverse effect in terms
of erosion when materials will be lifted from this area.
4. Sach Nala deposit :- The mineral deposit is located on the right bank of
Sach nala near upstream of Baloo and accumulated bulk of river-borne
materials which can be best utilized for construction purpose by lifting from it
manually. These materials varying in shape from sand to stone & bajri etc.
Since area being replenishable to sufficient extent, hence recommended for
purpose of mining lease.
1. No mining be carried out at the place along the river where the river bed is
seen to be higher than river bed.
7. Sherpur Deposit;-
38
This deposit is located in both down and upstream of Sherpur on left bank of
Ravi River and having bulk of river-borne materials which can be best utilized
for construction purpose. These materials varying in shape from sand to stone &
bajri etc. Materials are deposited in form of river bed in left bank of river Ravi.
Since this deposit is extended for considerable (nearly about 500 meters)
distances and is replenishable. Hence this area is also recommended for grant of
mining lease as it will not cause any adverse effect in terms of erosion when
materials will be lifted from this area manually.
8. Khairi Deposit;-
This deposit is located downstream near village khairi on right bank of Ravi
River. The deposit is spread over sufficient length and is mainly consist of
river-borne deposit & also materials derived from uphill side of surrounding
nalla apart from Ravi River. The deposit comprises of sand, stone & bajri.
However the proportion of stone & sand is maximum. Hence the site is
recommended grant of mining lease..
The mineral deposit is located near Surgani Downstream (from Surgani bridge)
upto village Kandla (previous auctioned area) along the river bed in form of flood
plain & Channel bars etc. It extends for great distance from Surgani bridge to
kandla downstream upto Chamera reservoir area. The deposit can be extracted
throughout the year except rainy seasons and deposit is connected through road
both at Sugani & Kandla. width of riverbed is varies from 50-300 metrs. In this
pocket. The mining is allowed only in left bank of suil nala except Surgani where
mining can be done fron either banks of river. The available minor minerals
deposit are in admixed form, comprises of sand, soil, silt, stone of different
39
dimensions. The available stone are of different sizes ranges from small pebbles to
huge boulders is available in great proportion. Near the Kandla, if the material
from the central raised portion is lefted, then it will deflect the flow of water flow
toward the centre rather than left & right banks, thus reducing the impact of
erosional activities on banks. It is, therefore, recommended that site is suitable for
grant of mining lease subject to conditions:-
D. Golli Nalla deposit:- This deposit is located near village Golli on Chamba-
Pathankot road Upstream. The deposit is accessible through road and can be lifted.
The materials comprise of mainly boulder, sand. The proportion of stone is
maximum. The deposit is restricted to very small extent. The collection/extraction
of deposit will not cause any adverse impact if it is carried out in systematic way.
The area is recommended to put for auction on following conditions:-
1. The collection of materials should be allowed from the side of water flow
towards the banks of nalla.
E. Naini Khad:-
This deposit is located upstream near village Nainikhad on
Chamba-Pathankot road. The deposit is of small little length and is mainly
consist of river-borne deposit & also materials derived from uphill side of
nallah. The deposit comprises of sand, stone & bajri. However the proportion of
stone & sand is maximum. Hence the site is recommended to put for auction.
The Bhadal, Suil , Tantgari and Baira Nala are important tributaries of Ravi.
The Ravi is a trans-boundary river flowing through Northwestern India and
Northeastern Pakistan. After the partition of India in August 1947, the waters of
the Ravi River, along with five other rivers of the Indus system (Beas, Sutlej,
Chenab, Jhelum and Indus), divided India and Pakistan under the Indus Water
40
Treaty, which was facilitated by the World Bank. Subsequently, Indus Basin
Project has been developed in Pakistan and many Inter Basin Water Transfers,
Irrigation, Hydropower and multipurpose projects have been built in India. The
Ravi river forms the biggest sub-micro region of Chamba district. From Bara
Bangal of Kangra district, it flows through Bara Bansu, Tretha, Chanota and
Ulhansa. The Ravi river merges with the Chenab in Pakistan. The well known
human settlement along the river are Barmaur, Madhopur and Chamba town.
Its total length is 720 km.
Catchment area of the Ravi River and its tributaries as given below in table-7

Table-8
The deposition in a river bed is more pronounced during rainy season although
the quantum of deposition varies from stream to stream depending upon
numbers of factors such as catchment, lithology, discharge, river profile and
geomorphology of the river course. The particle size may vary depending upon
the stage of river i.e. youth, mature and old age. In Chamba District it is
observed that annual deposition in various streams vary from 2 cms to 5 cms.
However there are certain geomorphological features developed in the river bed
such as channel bars, point bars etc. where annual deposition is much more even
two to three metres.It is also important to mention here that there is a provision
in the river/strem bed mining policy guidelines to allow collection of material
42
upto a depth of 1 metre where mineral concessions have been granted, but it is
noticed that during flood season whole of the pit so excavated is completely
filled up and as such the excavated area is replenished with new harvest of
minerals.
In order to calculate the mineral deposits in the stream beds, the mineral
constituents have been categorized as clay, silt, sand, bajri and boulder and there
average %age is taken into account. It is observed in different rivers/streams
that % age of boulders varies from 30% to 40%, bajri from 20% to 35 %, sand
from 20% 40% and silt and clay totalling from 10% 20 %. Boulder, bajri and
sand are the resource mineral i.e. usable mineral and rest is taken as the
waste.However during present calculation, the waste material i,e silt which vary
from 10 to 20% in different streams has also been included in the total
production. Further the Survey of India Topo-Sheets are used as base map to
know the extent of river course. The mineral reserves have been calculated only
upto 1.00 metre depth although there are some portions in the river beds such as
channel bars, point bars and central islands where the annual deposition is
raising the level of river bed thus causing shifting of the rivers towards banks
resuting in to cutting of banks and at such locations, removal of this material
upto the bed level is essential to control the river flow in its central part to check
the bank cutting. While calculating the mineral potentials, the mineral deposits
lying in the sub-tributaries of that particular stream/river has not been taken into
consideration. Since these mineral deposits are adding annually to the main
river, the mineral deposits will be much more.

Conclusion:
Entire District was traversed in four different traverses and were
inspected and studied thoroughly. During the traversing, it was observed that
whole District was drained out in mainly two basins i.e. Ravi and Beas basin.
The Three Rivers i.e. Ravi River, Suil River and their tributary i.e. Nallah/
Streams are drained out in Ravi basin whereas Chakki & Thulel khad and its
tributaries drained out in Beas basin. During the inspection, it is observed that
replenishment of the minor minerals in these rivers is more than that of its
lifting/collection. The exploitation of minor minerals are depends upon the
developmental works executed along the periphery of these river beds as most
of the townships are located in pockets along the periphery of these river beds.
Moreover these are very limited outlets from these rivers/ khads from where the
minor minerals are to be lifted.
Almost all the river/stream beds of the district have been defined as
forest land and without prior approval from competent authorities for diversion
of forest land for non-forestry use no mineral concessions shall be granted
64
Ministry of environment & Forest, Government of India. Therefore at present,
all rivers/ stream beds falling in Chamba District are banned for lifting/
collection of minor minerals for want of “No objection Certificate” from Forest
Department only hill slope mining mostly in private land are being carried out.
The lifting/ collection of minor minerals shall be carried out from the central
portions of the river beds, if allowed, so that proper and free flow channel the
water be developed, which ultimately prevents bank erosion.

to 500 mts D/S of bridges depending upon the site-specific conditions.
7 No approach road from PWD road shall be allowed to River/Stream beds
mining, unless lessee/contractor obtains written permission from XEN PWD for
making road leading to all intake places from the PWD Roads.
8 No mechanical mining through mechanical excavator including any other
earth moving machines like JCB, Bouldozer,Pocklain,Loders etc shall be
carried out in river or stream Bed by the lease holder or permit holder or
contractor as the case may be.
9 No boulder/cobbles/hand broken road ballast shall be allowed to be
transported outside the State from River/Stream beds, so as to reduce pressure
on the River/Stream beds.
10 No digging of more than 3 feet shall be allowed in River/Stream beds.
11 Every leaseholder shall supply in advance, the Registration Nos of
vehicle engaged in transportation of mineral from mining area to his industrial
unit. This would ensure checking of illegal vehicles carrying minerals.
12 Every lessee/contractor shall ensure that his labou/r does not involve in
fish poaching.
13. No blasting shall be allowed in river/stream beds.
26 General recommendations/conclusions:
During the preparation of the present report only 10 No.s of rivers/ streams has
been studied in detail, as the rest of the streams/rivers either have are very
narrow at most of the places and as such are fit for grant of mineral concession
for mineral based industries only in wider place, however it is also important to
mention here that because of the regular demand of sand, stone and bajri for the
developmetal activities in the respective areas, such streams are prone to illegal
mining, as such if any person/party applies for open sale of mineral on private
land, the mining for open sale may be granted to meet out the local demands
and Govt land on Public auction , or any exigency subject to the approval from
the joint Inspection Committee.These mineral concessions shall also reduce
demand load and‘ll be helpful to mininmise illegal extraction of minerals,
failure of which may result in to illegal mining at odd hours and shall be
haphazard and more detrimental to the local ecology.

Irrespective of it following geoscientific considerations are also suggested to be
taken into account during the river bed mining in a particular area:
1. Abandoned stream channels or terrace and inactive floodplains
may be preferred rather than active channels and their deltas and floodplains.
2. Stream should not be diverted to form inactive channel.
3. Mining below subterranean water level should be avoided as a
safeguard against environmental contamination and over exploitation of
resources.
4. Large rivers and streams whose periodic sediment replenishment
capacities are larger, may be preferred than smaller rivers.
5. Segments of braided river system should be used preferably falling
within the lateral migration area of the river regime that enhances the feasibility
of sediment replenishment.
6. Mining at the concave side of the river channel should be avoided
to prevent bank erosion. Similarly meandering segment of a river should be
selected for mining in such a way as to avoid natural eroding banks and to
promote mining on naturally building (aggrading) meander components.
7. Continued riverbed material mining in a given segment of the river
will induce seasonal scouring and intensify the erosion activity within the
channel. This will have an adverse effect not only within the mining area but
also both in upstream and downstream of the river course. Hazardous effects of
such scouring and enhanced erosion due to riverbed mining should be evaluated
periodically and avoided for sustainable mining activities.
8. Mining Lease (ML) areas should be demarcated on the ground
with Pucca pillars so as to avoid illegal unscientific mining.
9. The auction shall be done as per the recommendation /approval of
the Sub-Divisional Level Committee.
