Research on prediction of rock burst in deep hard - rock mines

Zhou Wen-lue

Abstract

Rock burst is one of geo - hazards frequently happened in the deep hard rock mines. Indexes of potential rock burst mainly are Elastic energy index, Linear elastic energy, Impacting energy index, Brittleness ratio and Russenses criterion . Based on analysis of some data of actual rock burst happened both in mine and in underground civil engineering all around the world, Russenses criterion is the potential rock burst index with obvious regularity. Taking the Dong-guashan Copper Mine as a case, in which the geological features are followed, the possibility of rock burst is predicted by using the Russenses criterion.
