摘要
为了提高软岩煤层掘进巷道顶、帮部支护效果,降低支护成本费用,保证巷道掘进安全,同煤集团四老沟煤矿机掘一队,在施工8106顶抽巷时提出了锚索桁架支护,施工期间未发生顶板破碎、煤壁片帮现象,保证了巷道安全快速掘进。
In order to improve the supporting effect of roadway roof and sides in soft rock seams, reduce the cost of supporting and ensure the safety of roadway driving, the first mechanical digging team of Silaogou Coal Mine put forward the anchor cable truss support during the construction of the 8106 top drainage roadway. No roof breakage and coal wall sheet phenomenon occurred during the construction period, which ensured the safe and rapid roadway excavation.
