摘要
以某矿9-301综采放顶煤工作面为研究背景,研究该工作面的支护阻力。研究结果表明:支架工作阻力为12000kN,可满足9-301综放工作面开采的要求;运输巷端头范围内所需整体支护阻力11037kN小于支架整体支护工作阻力,故该支护设计能满足选择运输巷端头支护的需要。
Taking 9-301 fully mechanized top-coal caving face in a mine as the research background,the supporting resistance of the face is studied.The results show that the working resistance of the support is 12 OOOkN,it can meet the requirements of 9-301 fully mechanized caving face mining;the overall support resistance 1 1 037 kN required in the end range of the transport roadway is less than that of the overall support of the support,so the support design can meet the needs of selecting the end support of the transport roadway.
