摘　　要：通过对综采工作面下分层上覆采空区块段过渡到实体煤块段开采技术进行探索,采取"追机移架"和"端头穿棚"方案,成功解决了下分层工作面上覆采空区块段顶板控制难题。创新采用"迎面斜交钻孔和上行穿层钻孔"及上隅角联合抽放瓦斯治理技术,杜绝采面推进到实体煤块段的瓦斯超限问题,并采取措施防止煤炭自燃。By lower layer overlying of fully mechanized working face goaf piece of period of transition to the entity coal mining technology to explore,take ＂move after machine frame＂ and ＂end wear tent＂,successfully resolved the layered roof control problem under goaf on the surface of block section.Innovation ＂oblique borehole and upward toward wear layer drilling＂ and joint drainage in upper corner gas control technology,put an end to mining face advancing to the entity coal roadway.the problem,and take measures to prevent the coal spontaneous combustion.

关 键 词：下分层 追机移架 斜交 穿层钻孔
