Abstract
In order to study the suitable coal recovery methods for the slope coal in Wucaiwan No.1 Open-pit Coal Mine,the article explores five existing mining modes of slope overburden resources in China,and proposes the design method combining overall steep slope mining with local steep slope mining.The results show that the steep slope mining technology is more suitable for the recovery of coal from the west slope to the boundary slope of Wucaiwan No.1 Open-pit Coal Mine.The limit angle of steep slope mining can not exceed 38°,and local steep slope mining can be carried out at+560 m and+575 m elevation.Through the economic comparison of coal mining volume,the optimal scheme is+560 m elevation mining,and the slope angle is 35°.关键词
