近距离煤层综采工作面巷道支护研究

Study on Roadway Support of Fully Mechanized Mining Face in Close Coal Seams

为提高近距离煤层综采工作面巷道的稳定性,改善巷道的支护效果,以山西程庄煤矿工作面皮带巷的地质条件为基础,对近距离煤层综采工作面巷道支护进行了研究。探讨了下部煤层巷道顶板稳定性及巷道支护原则,提出了巷道支护方案。该方案在现场得到了实施,支护效果良好。

In order to improve the roadway stability and support effect of fully mechanized mining face in close coal seams, based on the geological conditions of belt roadway in Chengzhuang Coal Mine of Shanxi, the roadway support of fully mechanized mining face in close coal seams were studied. This paper discussed the stability of the roof of the underlying seam roadway and the principle of roadway support, and put forward the roadway supporting scheme, which was implemented on site and of good support effect.
