【摘要】 开采沉陷是由于煤矿地下煤层的开采导致的一种主要的地质灾害类型,对土地的破坏非常严重。由于目前我国土地资源的日益紧张,在开采沉陷区修建建筑物成为发展方向,所以研究开采沉陷造成的地表变形,并对其稳定性进行评价,具有非常重要的意义。本论文应用概率积分法对肥城曹庄煤矿造成的地表变形稳定性进行了评价,取得了良好的效果。更多还原

【Abstract】 The mining settlement is one of the main geological disaster which caused by mining coal bed in the undergound,and the land was destructed seriously.China’s land resource is tight day by day,and construct the buildings in mining settlement areas has becomed a conception,so the research on the surface distortion,and the stability appraisal,is very significant.We use the probability integration to give an appraisal for the surface distortion stability of Feicheng Caozhuang coal mine,and has obtained a good effect.更多还原
