摘要
从软岩的工程特性、力学特性出发,对煤矿软岩进行了归类,即膨胀性软岩、高应力软岩、节理化、破碎化软岩和复合性软岩。提出了各种类型软岩的变形破坏机理及其应当采用的支护方法。
Based on the mechanical characteristics of soft rock,the raft rock in coal seam is catego-rized as expasive,high-stress,fractured and composite.Their deformation mechanism and suitable sup-port methods are introduced.
