 P19

Multidimensional data display, Discover and deal with all issues on-the-spot
In order to help engineers observe data quality anytime, our GD mainframes provide a wealth of data browsing tools, including data list of
measuring points (including data details), pseudo-sectional drawing, sectional drawing, and transmitting and receiving signal waveform.

All browsing tools can locate a certain measuring point, view the signal waveform of the measuring point, so as to evaluate the signal quality of
the point and the credibility of the result, and even retest the point if necessary.

Powerful roll-along survey, 3D and pseudo-3D profiling Roll-along testing, no repeated survey
points, robust roll along approach and highly efficient. Direct stacking of electrical resistivity,
satisfying clients’needs for data quality and survey efficiency enhancement
 P21

Automated stacking for data quality enhancement

During the data measurement process, it automatically analyzes signal strength and data
quality to determine whether long measurement period and stacking mode should be
activated. For sites with strong signal and good data quality, measurement system
continuously sweep and scans in high efficiency mode until bad data quality is detected,
in which long measurement period or stacking mode would be elaborated to enhance
data quality to the maximum extent. Clients can also set stacking amount according to
any survey points, survey layers or individual tasks

Groundwater Investigation by 2D Resistivity Scanning Technique at Amaryllis Bulbs Project of Siam Flower Bulbs Co., Ltd..
Nong Tak Ya Sub-district, Tha Muang District, Kanchanaburi Province Thailand

Groundwater resources found at Amaryllis Bulbs project of Siam flowers bulbs Co. Ltd. is meta-sedimentary aquifer that may
presents as low potential region. For a large amount of water supply taken from groundwater in agricultural use, geophysical
technology is needed to apply for developing high yield of water supply. Resistivity measurement has been
successfully found for detecting sub-surface feature of aquifer nature, in particular locating high potential groundwater zone.
The application of resistivity scanning technique using detail 2D imaging measurements including vertical electrical sounding
(VES) analysis (with 60 (or more) multi-electrode, 10m resolution) has been successfully applied to investigate for
groundwater with effective depth of about 100 m. The location of groundwater potential zone and target depth may be
useful for drilling process.

Groundwater investigation in Mankayan mining area, Philippines

Invited by Philippine DDCP Company, Geomative arranged GD-10 High-density electrical equipment operation training. Also
by the training, Geomative assistted DDCP to complete the investigation of the water content and surrounding geological
stability of the dam foundation in Mankayan mining area. Meanwhile the investigationprovided location reference for the
later construction of roads near the abutment.
The geographical location and surrounding conditions of the dam are as follows. The dam body has no concrete structure
and it is a simple earth-rock dam. Both sides of the east and west are high-lying slopes. The two measuring lines are laid out
as follows: ERT1, ERT2.

GEOPHYSICAL INVESTIGATION (2D ERT) OF THE KERUNGA LANDSLIDE, NABALPARASI DISTRICT, NEPAL

Geophysical exploration using two Dimensional (2D) electrical resistivity tomography (ERT) survey plays a significant role in
determining the subsurface resistivity distribution by making measurements on the ground surface. From these
measurements, apparent resistivities are recorded during the fieldwork, which are later converted to true resistivity using
appropriate computer software. These true resistivities are then converted to subsurface geological condition. The 2D
electrical resistivity profiling is capable of detecting boundaries between unconsolidated materials (overburden), rocks,
identifying weathered rock from fresh rock and contact between rocks of different lithology. The Kerunga landslide site is
located about 14.3 km NW form Kawasoti, 24 km along gravel and earthen road connecting Mahindra highway from Daldale.
The landslide located at Hupsekot V.D.C, ward -5, Kerungatol of Nawalparasi district. The location of the project sites are
shown in Figure 1.

2D ERT and IP surveys were conducted within the known gold mineral regions. Survey investigation discovered that there was a clear continuity zone at
shallow water region in zone A, spanning from depth not less than 80 meters, width around 200-300 meters and with length not less than 600 meters.
Survey also found that there is another similar region in zone B (northeast of the map) with approximately 400 meters in length. Survey shown that there is
a fault zone in north-south direction. Further survey exploration is recommended in both zone A and B at 30 degrees angle the north, with drilling depth not
less than 100 meters.
