| 摘 要： | 为减少单一赋权法在评价含水层富水性方面的不足,以韩家湾煤矿为例,在综合分析矿井地质、水文地质条件的基础上,选取含水层的厚度、岩心采取率、砂岩粒度指数、砂地比以及砂泥交互层数作为影响富水性的主控因素,分别利用模糊层次分析法、CRITIC法获得各主控因素的主、客观权重,通过博弈集合理论得到综合权重,进而基于GIS平台对含水层的富水性进行分区评价。结合钻孔单位涌水量、矿井出水点的分布结果对含水层的富水性分区结果进行验证。结果表明:研究区富水性整体呈现由中部向两侧逐渐减弱的趋势,该模型的评价结果与实际情况相吻合。

| Abstract: | To make up the deficiency of simplex weighting approach in aquifer water yield property assessment,taking the Hanjiawan coalmine as example,on the basis of mine geological and hydrogeological condition comprehensive analysis,choosing aquifer thickness,core recovery,sandstone grain-size index,total thickness of sandstone/strata thickness ratio and sandstone,mudstone alternating layer number as the main control factors impacting water yield property,using fuzzy AHP and CRITIC respectively to acquire subjective and objective weights,through game set theory has acquired synthetic weight,and then based on GIS platform carried out aquifer water yield property zonal assessment.Combined with borehole specific capacity,mine water outlets distribution data carried out verification for aquifer water yield property zonal results.The result has shown that the study area water yield property presented a gradually weakening trend from the center to both sides as a whole.The model assessed results are consistent with practicalities. |
