摘　　要：为解决锦丘煤矿建筑物下采煤地表沉陷控制问题,理论分析了膏体充填开采地表沉陷曲线及关键影响因素,并提出了覆岩稳定性判据。通过数值模拟,研究了膏体充填开采对地表开采沉陷的控制效果,提出了膏体充填开采工艺,最终进行了地表沉陷观测检验充填开采对地表开采沉陷的控制效果。现场监测数据表明,采用膏体充填时,地表最大沉陷量为96 mm,位于距离切眼493 m的采空区中心位置。研究成果可为建筑物下煤层充填开采提供借鉴。In order to solve the problem of surface subsidence control in mining under buildings in Jinqiu Coal Mine,the surface subsidence curves and key influencing factors of paste filling mining were theoretically analyzed,and the criterion of overburden stability was proposed.The control effect of paste filling mining on surface mining subsidence was studied through numerical simulation,and the paste filling mining technology was proposed.Finally,surface subsidence observation was conducted to verify the control effect of backfill mining on surface mining subsidence The field monitoring data shows that the maximum ground subsidence is 96 mm when paste filling is used,which is located in the center of the goaf 493 m away from the open-off cut.The research results can provide reference for coal seam filling mining under buildings.
