摘　　要：露天矿首采区以及拉沟位置的选择对露天矿的初期经济效益以及与后续采区的生产接续等问题有着十分重要的影响,是露天矿生产设计中最为重要的环节之一。由于影响首采区以及拉沟位置确定的因素众多,使用现有的单指标评价方法很难得到最优的结论。以我国某露天矿为例,选取8个指标建立评价体系,采用逼近理想点法建立起综合评价模型,并最终确定出露天矿首采区以及开段沟的最合理位置。评价结果表明:与传统的单一指标评价方法相比,采用逼近理想点法所构造的首采区以及拉沟位置选择的多指标评价模型具有更加简单、更加科学、更加可靠等优点。所采用的研究方法和思路对其他露天矿的首采区以及拉沟位置的合理确定有着一定的参考价值。Selection of locations of the first mining area and open segment ditch, one of the important links in open pit production, plays a significant role in improving the initial economic benefits and connecting the production in subsequent min- ing areas. However, due to many factors affecting the selection above, it is difficult to draw the optimal conclusion by the single parameter evaluation system. Taking an open pit mine for instance, eight indicators were selected to establish evaluation index system and comprehensive evaluation model was built by adopting TOPSIS. Then, the most reasonable location was determined. The evaluation result showed that compared with the single parameter evaluation system, the evaluation index system by TOPSIS became easier, more scientific and more reliable. The research methods and ideas used in the research have some reference val- ues for determining reasonable locations of the first mining area and open segment ditch in other similar open pit.
