松软破碎岩层一般是泛指湿抗压强度不高于(200公斤/厘米~2)、易于风化碎裂、浸水后很快崩解泥化的岩层。它们可能是整体状、块状、层状或软硬相间的组合岩层;结构面是软弱状态,岩体中的断层、节理和裂隙中充填着软弱物质。岩块尺寸和结合情况变化很大;整体强度低,泥质物含量高,往往还出现膨胀特性和流变特性。如金川镍矿的F_1断层和F_(16)断层压碎带,层间挤压和完整的混合岩组;柏坊铜矿22号断层附近的风化成泥状的白
Soft broken rock generally refers to the wet compressive strength of not higher than (200 kg / cm ~ 2), easy to weathering fragmentation, disintegration mud soon after soaking rock formation. They may be monolithic, massive, stratified or a combination of hard and soft rock; structural surface is weak, fault, joints and cracks in the rock mass filled with weak material. Rock sizes and combinations vary widely; overall strength is low and mud content is high, often with swelling and rheology. Such as the F_1 (16) fault crust, the intercalated extrusion and the complete mixed rock group in the Jinchuan Nickel Mine; the weathered muddy white near the No.22 fault in the Park Square Copper Mine
