摘　　要：为研究适合五彩湾一号露天煤矿边帮煤回收方式,探究了国内现有的5种边帮压覆资源开采模式,提出了整体陡帮开采与局部陡帮相结合的开采的设计方法。研究结果表明:针对五彩湾一号露天煤矿西帮到界边帮煤的回采,更适合于采用陡帮开采技术;陡帮开采时极限角度不能超38°,局部陡帮开采可在+560 m水平和+575 m水平标高进行开采;采煤量经济对比之下,最优方案为+560 m水平标高开采,边坡角35°。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°.
