The loess high-slope on the west side of water curtain cave colliery is an old landslide debris back-wall. There is an old landslide debris deposit at bottom of the slope. Surface water can infiltrate into the slope through loess uprightness joints and cranny. The groundwater flow gradually causes the formation of water cavities in the upper slope region. The slope further has loess stratification, obliquity (from 5° to 10°) and paleosols place. Surface water infiltrates into paleosols and induce water cavity exit with the top water cavity transfixion. The paleosols ideally prevents water. The loess stratification leans to ravine. The slope is unstable and will fail under the action of precipitations.
