摘要
针对黄屯硫铁矿地下开采面临地压活动、矿岩稳固性差、地表变形、河流涌入等技术难题,采用FLAC3D建立矿山数值模型进行三维数值模拟分析,揭示了黄屯硫铁矿地下开采的力学环境,分析了黄屯硫铁矿岩体应力、位移量、塑性区分布的规律,其分析结果对保证黄屯硫铁矿地下采矿作业的安全具有重要的指导意义。
Aiming at the technical problems of ground presses activities in mining face, poor stability of rock and ore, surface deformation and water inrush from the river in Huangtan pyrite mine, FLAC3D was adopted to establish the numerical model for the mine,and by the 3D numerical simulation the mechanical environment of underground mining was revealed, the rock stress, displacement and the distribution of plastic zone was analyzed. The results of analysis have important guiding significance to the safety of underground mining in Huangtun pyrite mine.
