Define about the Inclined Borings

Inclined  brings may also be used in exploration of  inclined strata and for the detection of weak pockets (lenses),  buried channels,  cavities and fault zones particularly in rock. Each inclined bore hole furnishes information on variations  in sub-surface conditions in both vertical and horizontal conditions. All the borings for exploration of narrow or elongated areas should not be located in a single straight line. However, sufficient number of borings should be made outside the main line to determine the dip and strike  to the surface strata.
