摘　　要：为解决某矿建筑物下遗留煤炭资源严重,矿井服务年限缩减的现状,提出了膏体充填技术,地表沉陷监测与经济效益分析表明:地表倾向测线下沉量最大值约为265mm,水平变形最大值0.368mm/m,曲率最大值0.008mm/m,倾斜最大值0.788 mm/m,各监测值均小于地表建筑物I级破坏程度值,同时采用膏体充填技术进行遗留煤炭的开采可收益约0.97亿元,具有良好的经济效益。In order to address the serious residual coal resources under a certain mine building and the reduction of mine service life,a paste filling technology has been proposed.Surface subsidence monitoring and economic benefit analysis show that the maximum subsidence value of the surface inclination measuring line is about 265 mm,the maximum horizontal deformation value is 0.368 mm/m,the maximum curvature value is 0.008 mm/m,and the maximum inclination value is 0.788 mm/m.All monitoring values are less than the level I damage level value of the surface building.At the same time,using paste filling technology to mine residual coal can generate a profit of approximately 97 million yuan,which has good economic benefits.
