摘 要:为了保证河曲露天煤矿转向期间煤炭资源的供应,结合露天矿实际生产条件,提出工作帮临时靠帮时采用纵采揭煤方式靠帮,优化了工作帮纵采揭煤时露天矿的运输系统,对比分析了内排无移动坑线方案与内排有移动坑线方案的经济性指标,确定了工作帮纵采区域最优运输方案为内排土场含移动坑线方案,为露天煤矿节省运费约700万元。In order to ensure the supply of coal resources during the turning period of Hequ Open-pit Coal Mine,combined with the actual production conditions of the open-pit mine,it is proposed to use the longitudinal mining and uncovering coal method when the working side is temporarily supported,and the transportation system of the open-pit mine during the longitudinal mining and uncovering coal of the working side is optimized.The economic indicators of the scheme without moving pit line in the inner row and the scheme with moving pit line in the inner row are compared and analyzed.The optimal transportation scheme in the longitudinal mining area of the working side is determined as the scheme with moving pit line in the inner dump,which saves about 7 million yuan for the open-pit coal mine.
