摘要:为了对目标含水层进行富水性评价、解决以往评价方法不能进行合理分区的问题,在充分利
用矿井增质、水文地质资料的基础上,建立了以单位通水量、渗透系数、含水层厚度、岩芯采取率,脆望性岩厚度比等5个指标为主控因素的含水层富水性评价指标体系,应用基于最大隶属度原则的模棚综合评判法,对含水层进行富水性评价分区。别入有效度理论,检验最大兼展度原则评价结果的有效性对不可信区域采用加权平均原则进行重新评价,最终确定全区富水性评价结果。结果表明,基于有效度的模糊综合评判法对含水层进行富水性评价是可行的,为含水层富水性评价提供了一种新的方法。

Abstract : In order to evaluale the waler abundance of the target axquifer and solve the problemn that previous evaluation methods can not efectively reflect water abundance zoning, On the basis of making full use of geological and hydrogeological data, a water abundance evaluation index system of aquifer was established, which was mainly controlled by five indexes, namely , unit inflow, permeability coeficient, thickness of aquifer, core recovery and thickness ratio of britle plastic rocks. The fuzzy comprehensive evaluation method based on maximum subordination principle was applied to perfom water abundance evaluation zoning of axquifer. The
evaluation result of maximum subordination principle ,the weighted
theory of degree of validity was introxuoed to test the validity of the e
average principle was adopted to reevaluale the untnusted region, and finally the evaluation result of water abundance in the whole region was determined. The results show that the fuzzy eomprehensive evaluation method based on validity is feasible to evaluale th water abunance of aquifer,and it provides a new method for the water abundance evaluation.
Keywords : aquifer; water abundance evaluation; fuzzy comprehensive evaluation method; clustering analysis; maximum subordination principle; the degree of validity

煤矿水害事故是仅次于瓦斯事故的煤矿五大灾
害之一,其一且发生往往会造成巨大的生命和财产损失)。煤矿水害的危害程度主要取决于矿井排水能力和突水发生时涌水量的匹配度,只有预先了解含水层富水性,根据富水性强弱提前设计排水设施的排水能力,才能最大限度地降低突水事故造成的危害。
