摘　　要：以某煤矿五2-11070综采工作面为背景,采用理论分析和现场实测的方法,对缓倾斜薄煤层综采工作面矿压显现规律进行了研究。研究结果表明,在充分采动的条件下,受煤层厚度的影响,自工作面下部到上部依次来压,整体压力强度较弱,工作面初次来压步距12.8 m,周期来压步距5.88 m;工作面中部支架压力大于两端支架压力,且下端头支架压力大于上端头;工作面整体支护效果良好,能较好地控制顶板。Based on s 52-11070 fully-mechanized working face in a coal mine,on-site measured research on the mining pressure behavior of fully-mechanized working face in gently inclined thin seam.The result showed that:under the condition of full mining,influenced by the thickness of coal seam,from the lower part of the working face to the upper part,the pressure is weaker.The initial weighting step is 12.8 m,and the cycle step is 5.88 m.The middle bracket pressure is greater than the bracket pressure at both ends,and the lower bracket pressure is greater than the upper end.The overall supporting effect of the working face is good,and the roof can be well controlled.
