摘要： 分析了补连塔煤矿12407工作面煤层赋存特征，利用FLAC3D软件建立了不同沙基比的三维地质模型，对开采引起的煤层覆岩移动和破坏进行了数值模拟；分析了现代煤炭开采过程中煤层覆岩的位移和应力分布规律，讨论了不同沙基比对覆岩移动和破坏的影响，可以预测采空区上覆岩层的损伤程度，并提前采取措施，可防止工作面溃沙、透水和保护地表植被。
关键词: 现代煤炭开采, 不同沙基比, 覆岩移动和破坏, 数值模拟
Abstract: The seam deposit features of Bulianta 12407 coal mining face were analyzed and the 3D geological model of the coal mining face was established by using the FLAC3D software, overlying rock movement and damage occurred by the coal mining operation is numerical simulation. The paper analyzed the displacement and stress distribution law of the strata above seam during the coal mining process and had a discussion on influence of different ratio of sand and bedrock on overlying rock movement and damage, that can forecast damage extent of the overlying rock in the mined-out area, and we can take measures to prevent to sand inrush and water inrush in the working face and protect plants on the surface.
Key words: modern coal mining, different ratio of sand and bedrock, overlying rock movement and damage, numerical simulation
