摘　　要：通过某钼矿开采的研究,了解和掌握地下矿山开采岩石顶板的稳定性及地表塌陷对岩移的预测和评价提供了指导依据,特别是对"三下"开采中地表构、建筑物的安全保护具有现实的指导意义。For predicting and evaluating the rock deformation in underground mining , a research on influence of stability of roof and surface subsidence on rock deformation in underground mining was implemented with a molybdenum mining case. Besides, this research provide the guidance of protecting surface buildings with ＂three-underground＂ mining .
