Abstract: Based on the specific geological deposit conditions of large-scale landslide in Shengli Coalfield, aiming at the safe and efficient recovery of coal resources covered by loose materials under the condition of high soft rock slope, the mining procedure of "cross mining and internal dumping ~ tailing pressure foot" is proposed to change the working line from linear type to Π type. And the safety precautions to ensure the smooth implementation of the project are put forward from the aspects of surface water and groundwater prevention, slope safety monitoring and so on. This paper calculates and analyzes the considerable recovery of resources and the economic benefit of reducing transportation distance and lifting height by adopting the mining procedure of "cross mining and internal dumping ~ tailing pressure foot", at the same time, the value of safe mining and the sustainable development of the mine are predicted.
