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*

提出了一种基于信息融合技术和可拓原理的煤矿井下环境安全等级评价新方法。依据煤炭生产现场的实际情况，应用可拓原理和基于多因素优化融合的思想，建立了煤矿井下环境安全等级的物元评价模型。该模型能够完整反映矿井环境的安全等级，实现了对矿井环境信息的定性与定量的集成描述。运用此方法对某矿井安全进行等级评判，得出的结论符合实际情况与工程实际，验证了该方法的有效性和可行性。

Novel evaluation approach for mine environment safety levels based on extension theory and information fusion

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.
