Analysis on steep slope mining operation way in Sandaoling Open-pit Coal Mine
SUN Jinliang
Abstract：With the increase of mining depth and dip angle of coal seam, Sandaoling Open-pit Coal Mine adopts steep slope mining operation way and determines the steep slope operation way in open-pit coal mine. Combining with the actual situation of the open-pit coal mine, the article analyzes and determines the steep slope operation parameters, increases the working slope angle, reduces the production stripping ratio, and improves the economic benefit.
