矿井老空水害危险性多源信息融合评价

Multi-source information fusion evaluation of mine goaf water damage

针对矿井老空水害机理复杂,影响因素众多且影响程度不一的难点,提出采用多源信息融合的方法进行矿井老空水害危险性评价:根据矿井老空水害特征构建老空水害评价指标体系,对主控因素进行网格化与归一化处理;采用层次分析法计算影响老空水害危险性的各主控因素权重,建立基于多源信息融合的矿井老空水害危险性评价模型。将模型应用于乌海能源五虎山矿井老空水害危险性综合评价,结果表明,该方法合理可行。

In response to the complex mechanisms and multiple influecing factors of mine goaf water,in this study,the method of multi-source information fusion was proposed to evaluate the risk of goaf water damage in mine.The evaluation index system of mine goaf water damage was constructed according to the characteristics of mine goaf water damage in mine,and the main control factors were treated with grid and normalization.The analytic hierarchy process(AHP)was adopted to calculate the weight coefficients of main factors affecting the risk of mine goaf water damage.An evaluation model of mine goaf water based on the multi-source information fusion was established.The model was applied to the comprehensive evaluation of mine goaf water damage in Wuhushan Mine of Wuhai Energy Co.,Ltd.The research results show that the method is reasonable and feasible.
