| Abstract: | 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. |
