摘要
分析了斜沟煤矿18503综采工作面材料顺槽采用沿空留巷技术的可行性,通过对巷道围岩受力情况的分析,计算出不同采高下加强巷道支护的方案和充填体的宽度。同时,介绍了沿空留巷的施工工艺以及在实际应用中取得的效果。
This paper analyzes the feasibility of using gob side entry retaining technology in 18503 fully mechanized working face of Xiegou Coal Mine.Through the analysis of surrounding rock stress of roadway,the scheme of strengthening roadway support and the width of filling body under different mining height are calculated.At the same time,the paper introduces the construction technology of gob side entry retaining and the effect in practical application.
