摘要
为了解决煤炭矿区水资源短缺的问题,从河南省六大煤炭矿区(鹤壁、焦作、永城、平顶山、义马、郑州)选取18个典型煤炭采空区,收集水文地质资料,采用AHP-集对分析法,构建以河南省典型煤炭采空区地下水资源利用作为目标层,以水量、水质、矿区水资源利用现状作为准则层,以矿井涌水量、平均煤厚、采空区面积、最大开采埋深、煤层顶板岩性、地质构造复杂程度、总硬度、溶解性总固体含量、pH值、氯离子含量、矿井水利用率、激励政策12个评价指标作为指标层的评价指标体系,对河南省典型煤炭采空区地下水资源利用进行评价,同时采用层次分析法对AHP-集对分析法评价结果进行对比验证。结果表明:两种方法的评价结果基本一致,河南省六大煤炭矿区典型采空区地下水资源利用可行性以焦作矿区最优、永城矿区最差,其余4个矿区居中且评价结果相近,说明采用AHP-集对分析法构建的河南省典型煤炭采空区地下水资源利用评价指标体系及评价结果是比较可靠的。
In order to solve the issue of water scarcity in coal mining areas,this paper collected hydro-geological data from 18 typical coal mines from six major coal mining areas of Hebi,Jiaozuo,Yongcheng,Pingdingshan,Yima and Zhengzhou in Henan Province and evaluated the utilization of groundwater resources in coal mine goaf areas,by using the AHP-set pair analysis to construct an evaluation index system with utilization of groundwater resources in typical coal mine goafs in Henan Province as the target layer;water quantity,water quality and current status of water resources utilization in mining areas were taken as the criterion layer;twelve evaluation indicators,including mine water inflow,average coal thickness,goaf area,maximum mining depth,roof lithology,complexity of geological structure,total hardness,total dissolved solids content,pH value,chloride ion content,mine water utilization rate and incentive policies were taken as the index layer.At the same time,it also evaluated the utilization of groundwater resources in coal goafs in Henan Province and compared the results with those obtained from analytic hierarchy process.The results show that the evaluation results of the two methods are basically consistent.The utilization feasibility of groundwater resources in typical goaf of six coal mining areas in Henan Province is the best in Jiaozuo mining area,the worst in Yongcheng mining area,and the other four mining areas are in the middle and the evaluation results are similar,indicating that the evaluation index system and evaluation results of typical goaf groundwater resources in Henan Province built by AHP-set analysis method are relatively reliable.
