金川镍矿是我国最大的硫化铜镍矿，以地应力高、矿体厚大和矿岩不稳固著称国内外采矿界。该矿体开采难度之大、充填成本之高备受国内外采矿界关注。近年来，随着矿床开采深度逐年增加已接近千米，采场面积超过1×10⁵ m²，高温、高压和高渗压的“三高”采矿环境日趋显著，不仅提高了采矿成本，而且还给矿山安全高效生产带来巨大压力。本文首先概述金川深部矿床采矿技术条件，然后明确采矿生产面临巷道和采场稳定性控制技术难题，分析采场围岩变形和岩层移动所潜在的灾变失稳风险。最后提出了金川深部矿体安全高效开采亟待攻克的技术难题，为金川深部资源开发能力和综合利用指明了方向。

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.
