摘要
为了进一步提高软岩煤层巷道顶板稳定性,防止顶板下沉造成顶板垮落、漏顶事故发生,大同煤矿集团雁崖煤业公司通过技术研究,决定对三盘区西翼5312巷顶板下沉区采取"注浆+施工U29型钢棚"等联合方法进行治理。实际应用效果表明,联合治理方法有效提高顶板稳定性,阻止了顶板进一步下沉,取得了显著成效。
In order to further improve the soft rock roadway of coal seam roof stability, prevent subsidence caused by roof caving roof, roof leakage accident, through technical research, Yanya Coal Industry Company of Datong Coal Mine Group decided to adopt the combined method of "grouting + Construction of U29 steel shed" to control the roof subsidence area of 5312 roadway in the west wing of sanpan district. The practical application results show that the combined treatment method effectively improves the roof stability and prevents the roof from sinking further, and achieves remarkable results.
