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 。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.
