基于熵权物元可拓模型的煤矿透水安全评价

Safety Evaluation for Coal Mine Flooding Based on the Extension Model of Entropy-weight and Matter-element

透水是煤矿安全生产过程中的主要灾害之一。为了准确评价煤矿水害安全状况,针对煤矿水害系统的复杂性,在对我国2000—2009年发生的68起煤矿透水重、特大事故原因进行分析的基础上,建立了合理的煤矿透水事故安全评价指标体系,并借鉴可拓学理论,融合熵权法构建了基于熵权物元可拓评价模型的煤矿透水安全评价方法,将其运用到某煤矿透水安全评价分析中,以验证该评价方法的可靠性。结果表明:待评煤矿透水安全评价等级为II级,即煤矿透水的安全状态为"较好",所构建模型的评价结果与实际情况基本符合,表明基于熵权的可拓学方法能够客观地评价煤矿透水的安全状态。

Coal mine flooding is one of the five major disasters in coal mine production.In order to accurately evaluate the safety of coal mine flooding,in view of the complexity of coal mine water disaster system,and based on the analysis of68major coal mine flooding accidents from2000to2009,this paper establishes a reasonable index system.From the extension theory,combined with the entropy weight method,the paper constructs the entropy extension evaluation model to evaluate the mine safety,which makes the evaluation results more objective and reasonable,and applies it to the safety evaluation of coal mine flooding.The results show that the evaluation grade of coal mine flooding is second level,and the coal mine flooding in coal mine is in better state and it is confirmed that the result of the model is consistent with the actual situation,which indicates that the extension theory based on entropy weight can objectively evaluate the safety of coal mine flooding.
