Study on Mechanism of Rock Blasting Fragmentation of Water Coupling Charge in Bore Hole

LUO Yun-gun,LUO Qiang,ZONG Qi (Dept. of Civil Engineering, Anhui University of Science and Technology, Anhui, Huainan 232001,China)  
according to the similitude law of blast and the equations of shock wave in water , this paper searched the bore wall pressure of bore water coupling charge structure and established rocky dynamical stress field under the function of blasting load ,and then obtained the crack area radius , the pulverizing area radius and the best uncoupling coefficient of bore water coupling charge in theory. Finally, it was examined and certified by engineering practice.
