摘　　要：根据我国煤矿的地质条件,将传统房柱式采煤提升为安全高效的短壁机械化采煤方法,并与充填技术相结合,针对充填技术特点合理布置采区巷道,充分利用充填物料凝固后的支撑强度,控制地表下沉和岩层移动,对煤柱、不规则块段、地质构造较复杂的煤层以及"三下"压煤等边角煤开采等提供了切实可行的技术途径,提高了煤炭资源回收率和开采效率。According to the geological conditions of coal mines in China, the traditional room pillar mining method was promoted to a safe and efficient short wall mechanized mining method, which is combined with the filling technology. According to the characteristics of the filling technology, the roadway in the mining area was reasonably arranged, and the supporting strength after the filling material solidifies was fully utilized to control the subsidence of the ground surface and the movement of the rock stratum. It has provided a feasible technical way for coal pillars mining, irregular blocks mining, mining of coal seams with complex geological structure, and the "coal mining underbuildings,railways and water-bodies" coal pressure equal angle coal mining, and so on, and has improved the recovery rate and mining efficiency of coal resources.
