基于改进未确知测度理论的矿床开采方式优选

为了判定矿床最优开采方式，基于改进的未确知测度理论，从环境、工程及技术经济等3个方面选取评价指标，建立矿床开采方式的未确知测度优选模型。该模型综合考虑矿床开采方式的影响因素，依据实际情况，对其进行定性定量分析，并引入博弈论计算各因素的综合指标权重，从而降低评价结果主观性，同时考虑了专家的经验因素，参考置信度识别准则进行等级判定，最后得出开采方式评价结果。结合国内某矿山实例，运用其对该矿床开采方式进行评价。研究结果表明：该矿山开采方式评价等级为Ⅱ级，与实际相符。

Mining Mode Optimization Based on Improved Unascertained Measurement Theory

In order to identify the optimal mining mode，based on the improved unascertained measurement theory，indexes of environment，engineering，economics were taken into account，an unascertained measurement model was established.The model considering the influence factors of mining mode，according to the fact， analyzing with qualitative and quantitative methods，introduced the game theory model to calculate comprehensive index weight of each factor.It reduced the subjective influence on the evaluation results of the part while the experts’experience was adopted.The evaluation results could be obtained with the credible degree criteria.Combining with an instance of a domestic mine，the mining mode was evaluated with the use of the unascer- tained measure theory.Research results shown that the evaluation level of the mine was Ⅱ，that was consistent with the fact.
