摘　　要：星村煤矿约80%煤炭资源被村庄压覆,村庄压煤的合理开采是矿方面临的一项重大课题。为切实掌握本矿的开采沉陷规律,在东翼一采区布置了地表移动观测站,并进行了相应的地表移动与变形监测,取得了较为完整的地表移动变形观测资料。分析了该矿的地质采矿条件,对一采区地表移动变形观测资料进行拟合计算与分析,得出如下结论:该矿千米大采深极不充分采动地表移动具有下沉平缓、下沉速度慢、移动期相对较长、无活跃阶段等特点。80% of coal resource in Xingcun Colliery is under villages,so rationally mining out coal under villages is a key problem for the colliery.In order to research mining subsidence rule,surface movement observation station was set up over East 1st mining area and whole surface movement data was obtained by surface movement and deformation monitoring.By calculating and analyzing observation data,the result was present that under deep extremely insufficient mining condition,surface subsidence was gentle,subsidence velocity was slow,movement time was long relatively and there was no active phrase.
