摘要
张双楼煤矿9200煤柱工作面回采期间先后过-500西二九煤副巷等12条老巷,根据巷道布置特征将老巷群分为同煤层老巷和穿层老巷进行分析,对-500西翼皮带运输巷、-500西副巷、西一九煤配风巷Ⅰ三条典型老巷进行了研究,提出扶棚支护、施工吊梁、木垛、爆破等加固方式。工程实践效果表明,工作面过老巷期间,顶底板稳定,实现了安全生产。
During the mining period of 9200 pillar face in Zhangshuanglou Coal Mine,12 old roadways,such as-500 West 29th coal auxiliary roadway,were successively passed.According to the layout characteristics of roadways,the old roadways were divided into old roadways in the same coal seam and old roadways through the seam.Three typical old roadways,namely-500 west belt conveyance roadway,-500 west auxiliary roadway and west 19th coal air distribution roadway,were studied and proposed to support them.Shed support,construction suspension beam,wooden pile,blasting and other reinforcement methods.The results of engineering practice show that the roof and floor are stable and the safety of production is realized during the working face passing through the old roadway.
