摘　　要：唐山矿业分公司将地面矸石、建筑垃圾等固体废弃物通过地面充填站的投料孔从地面垂直向下直接投料,进入矸石缓冲仓,由矸石仓放入胶带输送机等运输设备将其运输至充填工作面,借助自夯式充填综采液压支架等关键设备用固体充填物料充填工作面采空区,并靠固体充填物料的支撑作用对采空区的岩层进行控制,减少顶板的下沉和垮落,实现建筑物下安全开采。工作面充填矸石是解决矿山污染、资源浪费、地表塌陷的一个行之有效的方法,促进了绿色矿山的建设。Tangshan Mining Branch puts ground gangue,building garbage and other solid waste into gangue buffer chamber from the ground vertically intothe gangue direct feeding downward through the ground filling station feeding hole.The solid waste is transported to the work surface by the belt conveyor transportation equipment,and filled in goaf with the self-ram-filled hydraulic support and other key equipment.It can reduce the roof subsidence and collapse relying on the supporting role of the solid filling material to control strata on goafto realize safely mining under buildings.Working face filling gangue is one of the effective methods that it can solve the problem of mining pollution,resource waste and surface subsidence promoting the green mine construction.
