摘要

通过对露天矿山粉尘安全进行分析，确定了5个一级指标和20个二级指标进行评价，并将层次分析法确定的主观权重和熵权法确定的客观权重相结合，确定主观权重和客观权重；利用模糊数对专家打分进行综合，确定最终得分，二者结合构建露天矿山粉尘安全评价模型。以三个矿山为例，结果表明，A 1 矿山的露天矿山粉尘安全性明显优于其余两个矿山。研究表明，该模型适用于露天矿山粉尘安全评价，兼顾了主观性和客观性的典型特征，较好地反映了决策者的意图和指标的实际重要程度，使评价结果更加科学客观。所提出的方法为露天矿粉尘安全判定提供了参考。

A safety evaluation model of open-pit mine dust based on subjective and objective weighting method

By analyzing the dust safety of open-pit mines, five primary indicators and 20 secondary indicators are determined for evaluation, and the subjective weights determined by the hierarchical analysis method and the objective weights determined by the entropy weighting method are combined to determine the subjective and objective weights; the scores of experts are integrated using fuzzy numbers to determine the final scores, and the combination of the two is used to construct the evaluation model of the dust safety of open-pit mines. Taking three mines as an example, the results show that the open pit mine dust safety of Mine is A 1 significantly better than that of the remaining two mines. The study shows that the model is suitable for open pit mine dust safety evaluation, considering the typical characteristics of subjectivity and objectivity, better reflecting the intention of the decision makers and the actual importance of the indicators, and making the results more scientific and objective. The proposed method provides a reference for determining dust safety in open pit mines.
