【摘要】 以淮南某矿150801工作面为例,进行了高水复合矸石充填开采和全部垮落法开采相似模拟试验研究,并结合FLAC3D进行数值模拟。研究结果表明,高水复合矸石充填开采可有效控制采场上覆岩层的位移,降低覆岩活动与地表变形程度,对矿区环境保护、采空区治理,矸石处理、解放"三下"压煤具有重要意义。更多还原

【Abstract】 Based on the working face of a mine in Huainan, carries out the analogical simulative experimentation on the high-water material composite waste-filling technology and all carving methods.The study adopts the numerical simulation in combination with FLAC3 D. The results show that the highwater material composite waste-filling technology can effectively control the shift rule of overlying strata in stope,and ensuring reducing the activity of overburden rock and the deformation of the earth′ s surface. This technology is expected to play an important role in diggings′ environmental protection,the goaf treatment and the waste-filling management and the coal resources "three unders".更多还原
