摘　　要：结合斜沟煤矿23113综放工作面自身特点,提出了综放工作面液压支架单通道双头回撤工艺。以工作面中部为轴心,采用双主、副掩护支架支撑顶板,相向双头进行撤架,提高了回撤效率,为综采工作面回撤工艺研究提供了借鉴与参考。Combining with the characteristics of 23113 fully mechanized caving face in Xiegou Coal Mine, the single-channel and double-head withdrawal technology of hydraulic support in fully mechanized caving face is put forward. Taking the central part of the working face as the axis, the roof is supported by double main and auxiliary shield supports, and the roof is withdrawn by two opposite ends, which improves the efficiency of withdrawal and provides a reference for the study of withdrawal technology of fully mechanized mining face.
