不稳定顶板煤巷锚网索梁支护实践
Practices on bolt, mesh, anchor and beam support in coal drift under unstable roof condition of cataclastic rock mass
【摘要】 试验巷道顶板为碎裂结构岩体 ,介绍了此类结构岩体的主要工程地质特征。综合考虑锚杆兜掉和锚索悬吊两种作用设计了顶板支护参数 ,巷道稳定性观测表明试验取得成功
【Abstract】 The tests of combined support using bolt, mesh, anchor and beam are carried out in a coal drift surrounded by the cataclastic rock mass. The engineering geology feature of this rock mass are described in this paper. The parameters of roof timbering are designed based on the common action of bolting wire mesh wrapping and anchor hanging. The roof deformation keeping stable indicates that designed support pattern and parameters are suitable for the cataclastic structure roof.
