Abstract

Rock burst is one of the three big power disasters in deep mining environment and its quantities assessment method study is a hotspot issue. The analytical mode and method is set up for analysis of rock burst quantitative assessment in Deep Mining environment stress in this paper. The influence and sensibility of relative factors such as stress level, the size and damage degree of EDZ, Poisson's ratio and stress drop factors on the rock burst tendency and released energy during rock burst are discussed systematically. The research result indicate that: 1) with constant size of damage zone, the more rock damage, the more difficultly rock burst occur; 2) the rock burst tendency is insensitive to Poisson's ratio change; 3) with constant higher value of damage degree, the smaller damage zone size, the more difficultly rock burst occur, and there is inverse results in constant smaller value of damage degree condition.
