Application of Deep-hole Blasting Technology with Control Holes in Removing Hard Fault
Abstract：The efficiency of making the rock broken by the shear directly is low. It can be improved through using deep-hole loose blasting technology with control holes to rupture the rock firstly. Practice has proved that deep-hole loose blasting with control holes provides a way for the fully-mechanized mining face to pass the hard fault of rock smoothly.
