摘　　要：针对并行露天矿压帮内排二次剥离费用高的问题,提出了端帮倒三角留沟、排土场倒三角留沟、端帮水平留沟三种内排方案,根据端帮水平留沟方案,以二次剥离费用减少值、内排容量费用增加值、两矿单环内排运输费用增加值为变量,建立关于内排留沟高度的一元三次函数,并在黑岱沟露天矿进行了现场应用研究。结果表明,选用合理的留沟深度,可使矿区间端帮下三角煤回采经济效果最优。According to the high cost of twice stripping in parallel open- pit mine,the paper puts forward side- slope and inner dump inverted triangle and side- slope horizontal ditch diagram. Aiming at the side- slope horizontal ditch diagram,the cubics function about dumping ditch depth is set up by the second stripping cost reduction,capacity decreases cost recruitment and transportation cost recruitment. The results show that the optimal selection of reasonable depth of groove can make the economic effect of the triangle coal mining in the mining area.
