高水复合矸石充填技术研究

Study of High-water Material Composite Waste-filling Method and Technology

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。

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 carvirig methods. The study adopts the numerical simulation in combination with FLAC3D. The results show that the high- water 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 goal treatment and the waste-filling management and the coal resources ＂three unders＂.
