Effect of Protecting Borehole Wall and Congregating Energy on Blasting Protecting Borehole Wall

PU Chuan-jin,GUO Xue-bin,XIAO Zheng-xue,ZHANG Zhi-cheng(School of Environment and Resources,Southwest University of Science and Technology,Mianyang 621010,Sichuan,China)  
The isochromatic fringes graphs of smooth blasting and cutting seam blasting of pipe protecting borehole wall were obtained upon dynamic photo-elasticity experiments on both kinds of blasting.Analysis on the graphs show that shock effect can be greatly reduced for the existence of protecting face.The shear stress on smooth blasting of pipe protecting borehole wall between free face and protecting face reaches as high as 3.5 times,while the shear stress on cutting seam blasting of pipe protecting borehole wall between free face and protecting face reaches 1.75 times.Great power formed in free face direction for shaping smooth crack face of blasting and crashing medium,which shows that blasting protecting borehole wall has more effect of protecting borehole wall and congregating energy.
