Simulating Test on the Working Process of Explosion Gases

Wang Jialai(Tongji University, Shanghai, 200092)Cheng Yusheng(China University of Mining & Technology, XuZhou, 221008)  
By mechanical method, high - pressured air is produced to be used in simulatingthe breaking process of rock subjected to the explosion gases. Experimental results showthat this process is quasi - static and the static equilibrium equation based on tensile failure theory has a good agreement with practice. Consequently, the tensile failure natureof rock breaking by explosion gas is revealed.
