金川矿山深部工程地质研究现状及对策

Research Status and Countermeasures of Deep Geological Engineering in Jinchuan Mine

目前,金川矿山大部分已进入深部开采阶段,最大开采深度已经接近千米,矿区工程地质条件复杂,岩体软弱破碎,地应力大,开展金川矿山深部工程地质研究工作,有利于指导采矿优化设计、预测采场地压与失稳风险、评价采场巷道支护与变形,从而保障矿山经济高效开发和安全生产。本文从地应力、围岩、地质构造、支护、岩体强度等方面,分析了现阶段金川矿山深部存在的工程地质问题和研究深度,指出了今后的改进对策。

At present, most of the Jinchuan mines have entered the deep mining stage, and the maximum depth of mining is close to 1,000 meters. The engineering geological conditions of the mining area are complex, the rock mass is weak and broken, and the ground stress is large. The deep geological engineering research work of the Jinchuan mine is conducive to guiding the optimal mining design., Predict the risk of mining site pressure and instability, and evaluate the roadway support and deformation of the stope, so as to ensure the efficient economic development and safe production of mines. This paper analyzes the engineering geology problems and research depths in the deep-seated Jinchuan mine from the aspects of ground stress, surrounding rock, geological structure, support, and rock mass strength, and points out the future improvement measures.
