摘　　要：针对胜利一号露天矿首采区向二采区过渡的问题,提出了“L”缓帮过渡、扇形过渡及重新拉沟3种采区过渡方案,将此3种过渡方式又划分为“连续式”和“间断式”2种过渡类型,并对“连续式”过渡类型中“L”型转向和扇形转向2种采区转向方案的演化过程和经性济进行对比分析,得出胜利一号露天煤矿采用采区扇形转向方案为最优采区过渡方案,此方案无需增加额外排土空间,生产过渡顺畅,生产规模稳定,可为矿山生产企业创造更多的经济效益。Aiming at the problem of the initial mining area steering to the second mining area in Shengli No.1 Open-pit Coal Mine,the article presents"L"steering,sector steering and re-ditching,which are divided into continuous type and discontinuous type.The article compares the evolution process and economic economy of the two modes of continuous transition,obtains that the optimal transition method of open-pit coal mine is the sector steering scheme.The steering scheme achieves the goal of creating economic benefits for the production enterprise without increasing the external dump space,smoothing the production transition,stabilizing the production scale.
