Abstract: Because its complicated engineering geological conditions and Crack-expansion creep characteristic of rock mechanics, Jinchuan Cu-Ni deposit is always attracted attention to in mining engineering subject and rock mechanics subject at home and abroad. Recently, with the mining depth nearly reaching to 1000 meters, excavation intensity and excavation range gradually increasing, the fragmentation index of deep ore, the tectonic stress and the mining dynamic pressure are all tending to increase, which will cause a good many difficulties and potential security hazard. In this article, the author offers readers an important new technical train of thought about Jinchuan deep mining of high stress, based on systematically analyzing stability of the adit and the stope and movement of the rock strata,which Jingchuan Group has to solve.
