Q.1
Mark the correct objective:-
14
The stress is express as: (P=Load Area)
P/A
A/P
P.A
A/P x 100
The young modulus of a material is equal to
Stress/Strain within the elastic limit
Stress/Strain within the yield point
Strain/Stress the elastic limit
None of these
Most weather resisting rock is
Limestone
Marble

Quartzite
Slate
A dam in which entire force acting on it are directly transmitted to the foundation rock is known as
Gravity dam
Arch dam
Buttress dam
Earthen dam
The major resisting force in a gravity dam is:
Wave pressure
Water pressure
Uplift pressure
Self weight
Landslide occurs because of
Exhaustion of shear strength
Low moisture content in the material
High compressive strength of material
None of these
Landslide is the
Downward movement of slope material
Outward movement of slope material
Downward and outward movement of slope material
Downward and inward movement of slope material
The width of the ore body which can be economically mined is:
Stopping width
Assay width
Actual width
Grady width

Grab sampling consists in:
Picking pieces of ore at one place only
Picking pieces of ore at random to make up a sample
Picking pieces of coal only
Picking pieces of ore in a grid fashion
10) The lines joining points or equal vertical thickness in bed known as
Isopaches
Isothicks
Contours
Isochores
11) Polygonal method of reserve estimation is used when
Drill holes are equally spaced
Drill holes occur in rectangular grid
Drill holes are irregularly spaced
Drill holes are considered to form
12) Drift in mining terminology means:
The same as tunnel
The same as adit
A horizontal tunnel parallel to the strike of the load
Opening from the shaft, passing through the country rock and reach to the ore body
13) Cut off grade is:
The grade of ore ultimately fed to the beneficiation plant
The grade of ore below which mining which uneconomical
The grade of ore through the ore body
Always the same as average grade
14) Lines joining the point of equal elevation are known as:
Contours
Isochones
Isopeths
Stratum contours
