The incline section of the wall is called the 'batter,' and the flat part of the step is called the
'bench' or 'berm.
The production cycle also referred to as the mine unit operation that consists of ripping and dozing,
drilling, blasting, loading, and hauling
By means = dengan cara
Whereas = sedangkan
Ripping and dozing Typically, bulldozer, wheel dozers, and motor graders are the most common
equipment used. 3 Loading and hauling Nowadays, surface mining is conducted using shovels, front end
loaders or hydraulic shovels.

Rock falls and slope failures
he structural geology. That is, Principles of rock slope design the orientation and characteristics (such as
length, roughness and infilling materials) of the joints, bedding and faults that occur behind the rock
face.
Coincident – berimpit
Undergo = menjaalani
Rupture = pecah
The properties of discontinuities relative to stability include orientation, persistence, roughness and
infilling.
Uniform = seragam
Burial = penguburan
Confined = terbatas
he vertical stress, which is the major principal stress σ1, is equal to the weight of the overlying rock a The
horizontal stress, which is the minor principal stress σ3, also increases with the depth of burial due to
the effect of the grav and temperature = joint mechanism
1 Dip is the maximum inclination of a discontinuity to the horizontal (angle ψ). 2 Dip direction or dip
azimuth is the direction of the horizontal trace of the line of dip, measured clockwise from north (angle
α) In defining the orientation of a line, the terms plunge and trend a
The only general rule that applies to investigation for rock slope design is that information is required on
geology, rock strength and ground water. The sonic velocity of the elastic wave will be greater in higher
density material, and in more massive rock compared to low density, closely fractured rock;
Lumps = bongkahan
Susceptibility = kepekaan
