Jinchuan nickel mine is well known for its high crustal stress, thick and large ore body and unstable ore rock in the mining industry. It is well noted by domestic and overseas mining industry for the the huge orebody mining difficulty and high filling cost. In recent years, with the depth of mining approching 1000 meters and stope area exceeding 100 square kilometers, "three high" mining environment, which is characterized by high temperature, high pressure and high osmotic pressure, is more and more significant. As a consequence, the safty of deep ore body and the mining efficiency are seriously challenged. In this thesis the problems and challenges faced by deep mining is overviewed firstly. Then the control problems of roadway and stope face stablity faced by mining production are stated. Catastrophe risk of instability caused by stope wall rock deformation and rock strata movement is analyzed. At last, proposing technical difficulties that the jinchuan deep mining safely and efficiently should be overcame, providing clear research direction for improving development ability and the comprehensive utilization of resources.
