高河煤矿W4301工作面顺槽变形破坏特征及控制措施

Deformation and failure characteristics and control measures of groove along W4301 working face in Gaohe Mine

以高河煤矿W4301工作面顺槽支护作为研究对象,分析工作面顺槽变形破坏的特征,结合W4301工作面顺槽的实际情况,提出了"锚网索+梯子梁"复合支护方式,从现场支护设计情况来看,能较好的满足现场支护需要,有效控制W4301工作面顺槽围岩出现的大变形破坏问题,对于类似巷道的支护有一定的借鉴意义。

The slotted support of the W4301 working face in Gaohe Mine was take as the research object, the analysis of the characteristics of the deformation and failure of the slotted working face, combined with the actual situation of the slot in the W4301 working face, a composite of "anchor net cable + ladder beam"support method was got, from the point of view of on-site support design, which can better meet the needs of on-site support, effectively control the large deformation and failure of the surrounding rock in the W4301 working face, with certain reference significance for similar roadway support.
