Abstract
The shaped charge were made for identifying the effect of controled blasting using relatively low VOD explosive for cutting rock mass with changing quality and thickness of metal liner. The metal liner was attached on both sides of a charge for directional cutting, when the shaped charge exploded in rock mass. Also, a efficiency of shaped charge was identified by concrete member experiment. And a center guide used for maintaining stand-off between shaped charge and hole wall. A case of Fe liner of thickness 0.8mm formed the deepest notch of experiments and the directional cutting of concrete member was identified.
