Analysis on the Influence of Borehole Factors on Open Bench Blasting Effect

PU Chuan-jin(Southwest University of Science and Technology,Mianyang 621010,China)  
Borehole is one of the key factors which influence blasting effect in the borehole blasting.Gradient,diameter,extra-deep,stem length,hole space,row space and minimum resist line of borehole are analyzed in this paper.This may be reference to design of bench blasting.
