摘　　要：以锦丘煤矿162-102工作面为研究对象,探“三下”压煤环境下充填开采法对地表沉陷的影响。结果表明:充填开采与垮落开采地表沉陷规律相似,充填开采地表沉陷量与距离采空区中心位置成反比,最大下沉量为96 mm;从G观测线可以看出,随采空区范围扩大,超前影响范围有缓慢增加的趋势;与垮落开采相比,充填开采能更好地控制采空区地表下沉量,各参数都远小于地表建筑物I级破坏临界值。Taking the 162-102 working face of Jinqiu Coal Mine as the research object,this paper probes into the influence of the filling mining method on the surface subsidence under the "three under" coal pressure environment.The results show that the law of surface subsidence in backfilling mining is similar to that in caving mining,the amount of surface subsidence in backfilling mining is inversely proportional to the distance from the center of the goaf,and the maximum subsidence is 96 mm.From the G observation line,it can be seen that with the expansion of the goaf,the leading influence area tends to increase slowly.Compared with caving mining,filling mining can better control the surface subsidence of goaf,and the parameters are far less than the critical value of grade I failure of surface buildings.
