It is the basic technique used in mapping surface of underground exposures. 

• Structural Mapping

• Scan Line Mapping

• Stereo-netting 

• Scan Line Survey

Shear strength is a material’s ability to

• withstand weathering 

• resist sliding on a plane

• resist compression

• resist tension

The fractures on which identifiable shear displacement has taken place.

• faults

To explore a horizontally lying deposit, how will you best position your holes?

• inclined at a shallow angle

• vertical

• none of these

• inclined at a steep angle

Strain is defined as

• the change in length divided by the force that caused the deformation

• the force causing the deformation divided by the change in length

• the original length divided by the change in length

• the change in length divided by the original length

A rock mass classification that quantifies discontinuity by the ratio of the length of the individual pieces of core recovered in a drill, having lengths of 10 cm or longer, and the total length of drill run:

• RMR

• RQD

• fracture spacing

• work index

When the rock reach its maximum stress, usually averaged over a plane, the rock can sustain under a given set of conditions.

• yield

• durability

• strength 

• hardness

Opening or connection to the surface from an underground excavation. 

• adit

• manway

• entry

• portal
