基于耦合评价模型的采场污染等级研究

Study on Stope Pollution Level Based on Coupling Evaluation Model

针对目前采场作业环境复杂,现有评价方法比较单一模糊的情况,提出引入集对分析中联系数来描述采场作业环境中各影响因素与评价标准间的模糊性,并用改进的三角模糊数对集对分析中同异反模型差异度系数的连续过程进行刻画和描述,最终构建出基于联系数的动态三角模糊数决策模型。通过在实例分析中采用矿井的监测数据进行评价,发现构建模型评价结果与其它方法基本一致,表明多元联系数值的大小能更形象反应不同区段采场环境的污染程度,可以为采场作业环境评价提供一种新的方法,所得结果更加客观和精确,对现场生产有重要的现实意义。

In view of the complexity of the stope working environment and the single fuzzy evaluation method,the connection number in set pair analysis is introduced to describe the fuzziness between the influencing factors and the evaluation standard in the stope working environment.The continuous process of the difference coefficient of the same and different inverse models in the set pair analysis is described and described by the improved triangular fuzzy number.Finally,the dynamic triangular fuzzy number deci-sion model based on the connection number is constructed.Through the evaluation of the monitoring data of the mine in the case analysis,the evaluation results of the constructed model are basically consistent with those of other methods,indicating that the size of the multivariate connection value can more vividly reflect the pollution degree of the stope environment in different sections,which can provide a new method for the evaluation of the stope working environment.The results are more objective and accurate,and have important practical significance for the field production.
