摘　　要：利用水化学找铀,有成本低、效率高、速度快等特点,在寻找可地浸砂岩型铀矿也有明显的效果.但是在找铀过程中仅用水化学成份、氡含量、酸碱度和氧化还原电位等数值进行描述,说明它们与铀矿化的关系,这种单一因素的描述不能综合反映与铀矿化的联系程度,以定量评价铀矿化与上述因素的关系,从而影响了水化学找矿的效果.通过模糊数学方法建立数学模型处理水化学数据,已知可地浸砂岩型铀矿的特征值为参数进行定量评价未知区铀成矿的前景,使该方法成为今后铀矿预测中一种可靠有效的水文地质方法.A model was established through fuzzy mathematical analysis for the treatment of hydrochemical data. A quantitative appraisal of the prospect of uranium mineralization is completed based on a set of hydrochemical data acquired from the known in-situ leachable sandstone-type uranium, including radon content, acid-alkali ratio, oxidized and reduced electronic potential, hydrocarbonate radical and uranium content in water. This method is becoming a reliable hydrogeological way of predicting uranium deposits in the future.
