东海煤矿高应力煤巷锚网索支护研究

Study on the Bolt-mesh-anchor Supporting Technique in the High Stress Coal Roadway

为了研究锚网索支护技术在高应力煤巷中的适用性,对东海煤矿32号层左九巷道原锚网索支护方案出现的问题和软岩巷道破坏原因进行了分析,根据有限元计算结果确定支护关键部位。在此基础上,对支护方案进行优化设计,确定了具体的耦合支护参数。

In order to study on the applicability of the bolt mesh - anchor technique in the coal roadway, this paper analyzes in the problems occurring in the former bolt - mesh - anchor supporting scheme adopted in left 9 coal roadway and the causes of the deformation - failure of the high stress coal roadway, and determines the key parts of the supporting according to the finite element analysis, and based on this, makes optimum design of the supporting scheme, and determines the concrete coupling supporting parameters.
