摘　　要：矿井深部开采时,地表仍会出现沉降变形破坏,使地表上的建筑物受到损伤,从而威胁到人的生命和财产安全。为探究隆博煤矿深部开采作用下地表变形规律,本文利用现场实测数据进行分析。研究结果可知:随着煤层开采距离的推进,地表下沉值、倾斜值和曲率值总体随之增大;当开采距离到达一定程度后,下沉值会减小。充分开采前,地表下沉速率随着时间和煤层开采推进距离的增加而增加;充分开采后,地表下沉速率逐渐减小。该研究成果具有一定的社会意义,可为生产提供指导。During deep mining,subsidence deformation and destruction of the surface will damage the buildings on the surface and threaten people's life and property.The paper uses the field measured data to analyze the law of surface deformation during deep mining in Longbo Colliery,whose research results show that with the advance of coal seam mining distance,surface subsidence value,slope value and curvature value will increase.When the mining distance reaches a certain extent,the subsidence value will decrease.Before full mining,the surface subsidence rate increases with the increase of time and advancing distance of coal seam mining,but after full mining,the surface subsidence rate decreases gradually,having certain social significance and providing guidance value for future production.
