基于未确知测度理论的露天矿总承包安全评价
发布时间：2018-09-03 06:34
【摘要】：基于未确知测度理论,建立了露天矿总承包安全评价指标体系。采用专家打分法对所选取的25项综合评价指标进行综合打分,并做定量分析,确定了在不同评价等级下各指标的未确知测度,并利用熵计算各指标的权重,最后根据置信度识别准则得出露天矿总承包安全评价结果。结合某露天矿实例分析表明,该方法计算合理,明确了总承包开采下该露天矿的安全现状,为露天矿总承包安全评价提供了一种新的思路,可在类似工程环境中推广应用。
[Abstract]:Based on the theory of unascertained measure, the evaluation index system of general contract safety of open pit mine is established. The expert scoring method is used to synthetically score 25 comprehensive evaluation indexes selected, and quantitative analysis is made to determine the unascertained measure of each index under different evaluation levels, and to calculate the weight of each index by using entropy. Finally, according to the confidence recognition criterion, the result of general contract safety evaluation of open pit mine is obtained. The analysis of an open pit mine example shows that the method is reasonable, and the present safety situation of the open pit under general contract mining is clear, which provides a new idea for the general contract safety evaluation of open pit mine, and can be popularized and applied in similar engineering environment.
