摘要
针对8307工作面回采过断层期间,工作面煤壁出现严重片帮现象,导致工作面端面距加大、端面破碎严重,局部顶板出现冒漏,严重威胁着工作面安全高效回采的问题,综采二队根据工作面回采现状,提出了“煤壁注浆加固+超前管棚+铺设柔性纤维网”联合支护技术。通过实际应用效果来看,采取联合支护技术后,工作面在后期回采时未出现煤壁大面积片帮、顶板冒漏事故,取得了显著应用成效。
According to the current situation of the 8307 working face,the coal wall of the working face has serious flake gang phenomenon,which leads to the increase of the working face end distance,serious end breakage,and local top plate bubble leakage,which seriously threatens the safe and efficient recovery of the working face."Through the practical application effect,there is no large area of coal wall flake and roof leakage accident in the later back mining after adopting the joint support technology,which has achieved remarkable application effect.
