基于熵权法-层次分析法耦合赋权的多源信息融合突水危险性评价

Water inrush risk assessment with multi-source information type fusion based on EWM-AHP comprehensive weighting

为了建立更加准确的煤矿巷道底板突水评价模型,本文将层次分析法和熵权法相结合,并通过耦合赋权的方法,建立综合权重耦合模型确定综合权重。该模型在提高权重可信度的基础上,进一步建立结合两种脆弱性评价方法(模糊综合评价法和脆弱性指数法)的多源信息融合模型。在分析良庄井田15号煤层地质资料的基础上,选取8个主控因素进行分析。结果表明,建立的多源信息融合模型符合实际生产情况,对矿井生产具有实际指导意义,与原有方法相比,更有利于指导矿井的安全生产工作。

In order to establish a more accurate evaluation model for water inrush,the analytic hierarchy process and the entropy weight method were used to establish the integrated weight coupling model to determine the comprehensive weight by means of coupled weighting.On the basis of the model increases the weight of credibility,furthermore,a multi-source information fusion model combining fuzzy evaluation method and vulnerability index method with two methods of vulnerability assessment was established.Based on the analysis of the geological data of coal seam No.15 in Liangzhuang minefield,eight main factors were selected for analysis.The results showed that the established multi-source information fusion model was in line with the actual situation.The established model had practical guiding significance for mine production,and it is more advantageous to guide the safe production of mine than the original method.
