摘要
简要论述了乌拉嘎金矿团结沟西采场软岩边坡宏观破坏特征：小于内摩擦角的滑面倾角、大变形、渐进式破坏，指出了泥化夹层水膜面化作用机制，阐明了以疏排水为主的防治对策。
Macro-characteristics of soft rock landslide at wester'n mining stope of Tuanjiegou mine,Wulaga Mines,are concisely discussed,including dip angle of slip plane which is smaller than inner friction angle,large deformation and graduate failure.The mechanism of intercalated clay layer water film is given. Controlling methods with drainage as major one are explained.
