The slide release process in big dip face by adjusting the tilt, consistent with "Coal Mine Safety Regulations"provisions, but also reduce the cost of inputs, in line with the requirements of high yield and efifciency face. At the same time, through the face of the shrinking surface mining of coal pillars to reduce losses and improve the recovery rate of coal resources, and create considerable economic beneifts.
