摘　　要：扩能开采方案的选择不仅影响两个采区衔接的优劣程度,还会影响整个矿区开采的整体规划,为了更好地提高露天煤矿转向效率和经济效益,对采区最佳接续工程位置和转向方案的优选方法进行研究。本文基于新疆某露天煤矿扩能开采首采区的拉沟位置和转向方式的选择问题,通过建立模拟开采模型并结合拉沟位置选择的原则,提出四种扩能开采拉沟位置的方案,对比得到方案4的实施能够有效解决产能接续问题,并且剥采比较低,经济效益好。In order to improve the steering efficiency and economic efficiency of the open pit coal mine, the optimal location of the mining area and the steering plan are studied. In this paper, based on the selection of trenching location and steering method for the first mining area of an open pit coal mine expansion mining in Xinjiang, four options of trenching location for expansion mining are proposed by establishing a simulation mining model and combining the principles of trenching location selection, and the implementation of Option 4 can effectively solve the capacity succession problem, and the stripping comparison is low and the economic efficiency is good.
