AN id=EnChDivSummary name="EnDivSummary">Starting from engineering geologic conditions, hydrogeologic conditions, the human engineering activity and etc., this paper analyzes the formation mechanism of the high loess slope at an open-pit mine of Shanxi Pingshuo Coal Industry Corporation. The deformation of the landslide presents remarkable failure character of trail, the deformation and failure process can be divided into the unloading deformation,creep-crack, sliding quickly and stabilizing gradually. According to the formation mechanism of the landslide, some preventive countermeasures are put forward.
