粤东北某铀矿床矿坑涌水量预测方法研究

Research of Water Yield Prediction of Mine about a Uranium Deposit in Northeast of Guangdong Province

介绍某铀矿床各含水层的特征,分析矿坑充水因素,深入探讨前人矿坑涌水量预测中存在的问题。通过研究RQD与深度的关系及RQD与渗透系数的关系,对水文地质比拟法预测矿坑涌水量的公式进行修正,并建立了适合该矿床矿坑涌水量预测的水文地质比拟法。

This paper Introduces characteristics of the aquifer about a uranium deposit and analyzes the factors of water filling.It also researches on the existing problems of water yield prediction of mine.Based on studying the relationship between RQD and depth,RQD and permeability coefficient,the author revises the formula of water yield of mine which predicted by the hydrogeological analogue method in order to suit for this deposit.
