运用三维有限差分方法分析矿山深部开拓力学过程,对比了矿山开采历史和进行技术改造后围岩的应力、位移和破坏情况,预测了矿山深部开拓形成后可能出现的地压灾害风险及其发生位置,提出了可行的技术措施.%Three-dimensional finite-difference calculation method was used to analyze the mechanical process of deep development of mine. Then, the mining history, the stresses, displacement and destruction of the surrounding rocks after technical reconstruction were compared, and the potential happening possibility and place of ground pressure disaster after deep development were forecasted. Finally, the viable technical measures were given.
