基于相似模拟下地表沉陷的相似理论研究

Study on similarity theory of surface subsidence based on similarity simulation

本文以大同煤矿集团恒宝源煤业有限公司一采区8105工作面4~#煤层在综合机械化开采下地表沉陷为研究对象,通过相似模拟实验数据分析与地表沉降实测数据对比,结果表明:来压步距及地表最大沉降值与实际地表沉降相符,为矿井安全生产提供了参考。

In this paper,the surface subsidence of the No.5 coal seam in the 8105 working face of the No.1 mining area of Hengbaoyuan Coal Industry Co.,Ltd.of Datong Coal Mine Group is taken as the research object.By comparing the data of similar simulation experiment and actual measurement of surface subsidence,the results show that the distance of weighting step and the maximum value of surface subsidence are consistent with the actual surface subsidence,which provides a reference for mine safety production.
