Novel evaluation approach for mine environment safety levels based on extension theory and information fusion
基于可拓理论与信息融合的煤矿井下环境安全等级评判方法

On the basis of multi-sensor information fusion technique and extension theory,this paper presented a novel method about safety rank evaluation system for mine environment.According to the actual situation of coal production,based on the thought of multi-index fusion and extension theory,constructed a matter-element model that could completely indicate the mine environmental safe level.The information of mine environment could be described by qualitative and quantitative manners.As an example,the proposed method was used to assess a concrete application.The result shows that the method is feasible and effective,and the evaluation results are more reasonable.
