Slope geological profile
The mine excavation slope is selected as engineering background, and the slope angle is 26°. The slope is composed of topsoil, sandstone and mudstone from top to bottom. Among them, the thickness of topsoil is 15 m, the density of topsoil is 13.1 kN/m3, the cohesion of topsoil is 40 kPa, the internal friction angle of topsoil is 14.7°. The thickness of sandstone is 24 m, the density of sandstone is 19.3 kN/m3, the cohesion of sandstone is 75 kPa, the internal friction angle of sandstone is 16.9°. The thickness of mudstone is 30 m, the density of mudstone is…
