摘要
为了最大限度解放"三下"煤炭资源,同时更好地保护地表建筑物,以邯矿集团陶一煤矿充九采区超高水材料充填条带开采为工程实例,采用FLAC^(3D)数值模拟和现场实测的方法,对超高水材料充填条带开采岩层移动和地表沉陷规律进行研究,分析不同充填条带开采方案地表移动规律,得出最优合理开采方案。结果表明:充填条带开采,地表建筑物均控制在Ⅰ级破坏范围内,地表与基本顶下沉是协调同步的;模拟与实测结果基本吻合,实测地表减沉率达到95%。
In order to maximize the utilization of coal resources under buildings,railways and water bodies,and better protect buildings on surface,the surface subsidence law for strip mining with super high-water material is studied through FLAC^（3D）numerical simulation and field measurement method, combining with the specific engineering examples. The surface movement law of different filling strip mining scheme is analyzed to obtain the optimal scheme. The results show that： the buildings are within gradeⅠfailure degree and subsidence of surface and basic roof is synchronized under strip mining with backfilling; the simulation and measured results are basically consistent,the surface subsidence rate is up to95% according the measured data.
