在厚火成岩下采煤,因火成岩硬度大,不易冒落而容易诱发冲击性地质灾害。为了研究火成岩下开采沉陷规律,解决火成岩下开采地面破坏及建筑物保护问题,建立了地表移动观测站。根据火成岩厚度分布情况,结合数值模拟计算,确定了煤层开采后火成岩随下伏岩层呈整体下沉。利用岩移预计软件计算无火成岩条件下地表变形,与实际观测结果对比,分析火成岩下采煤地表移动规律。

Coal mining under thick igneous rock may cause the serious geological disaster because of the hardness of ig-neous rock and difficulty in caving. In order to study the surface subsidence law of coal mining under the igneous rock,and solve the problems induced by mining,such as surface damage and building protection,the surface movement observation sta-tions were established. According to the distribution of igneous rock thickness,combining with numerical simulation,it is found that the igneous rocks with the underlying stratum subsided as a whole. Then,the mining surface subsidence with no igneous rock was gained by using the rock movement prediction software,and compared with the actual observed results to analyze the surface subsidence law during coal mining under thick igneous rock.
