摘　　要：对西部石嘴山一矿38区深部+600m轨道巷开采扰动区进行了全面的工程地质调查.采用MOTIC-BA300POL型偏光显微镜等综合分析了砂岩、泥岩的矿物成分、物理性质、自然状态以及饱和状态下的力学及变形特性.结合现场围岩变形、应力监测与构造异常探测等,研究了深部复杂应力环境下松软岩层力学特性.This paper investigated the comprehensive in-situ engineering and environmental characteristics of No. 38 excavation disturbed zone （EDZ） at the depth of 600 m in Shizuishan Mine in western China. The mineral composition, physical characteristics and mechanical properties in nature and saturation conditions of sandstone and mud-stone were analyzed by microscope and material testing machine. The collapsing regularity and stress characteristics of soft rock in the complex stress environment of deep mining were quantificationally gained based on deformation and stress monitoring and tectonic detecting.
