Discussion on Shear Stress of Cutting Seam Cartridge Blasting

LI Xian-yin,PU Chuan-jin,XIAO Ding-jun(College of Environmental Engineering,Southwest University of Scienceand Technology,Mianyang 621002,China)  
In the paper,the fracture failure characteristic of rock was firstly studied by the impact damage of rock samples under shear stress,and then the cutting seam cartridge blasting was numerically simulated.The results showed that shear stress was obvious in the lancing of the cutting seam tube,which make the blasting crackle formed from the lancing at first,thus have the effect of directional fracture to seam.
