摘　　要：根据矿山的开采境界,依据露天矿拉沟位置的选择原则以及该矿山的特殊地质地形条件提出了3种首采区及拉沟位置方案,建立了含7种评价指标的评价体系,引入基于可变权重的理想点法建立的分析评价计算模型,求解得出各方案的理想点距离和贴近度,按照贴近度取值标准确定了最优的首采区及拉沟位置方案。According to the mining state, the selection principles of open-pit mine trenching position and the special geological condition, the article puts forward three kinds of first mining area trenching position schemes, and establishes seven evaluation system of evaluation indicators. The article establishes the analysis and evaluation model based on the ideal point method with variable weight, obtains the ideal point distance and closeness degree, according to the similarity value standard to determine the optimal first mining area trenching position.
