摘　　要：该文以沙子江矿床为例,采用水文地质比拟法预测矿坑涌水量,计算后发现所得结果与大井法所得数值相差较大。因为,在研究中忽视了渗透系数K随深度变化这一重要规律,影响了矿坑涌水量的预测。利用修正后水文地质比拟法公式,计算得到的矿坑涌水量与大井法所得数值误差较小。因此,可以建立适合本地区的预测矿坑涌水量的水文地质比拟法。In this paper, taking the Shazijiang deposit as an example,the water yield of mine deposit is predicted by using the hydro-geological analogy method. But the calculated results show that the difference is large between the calculated results and the calculated values by big well method. Because in the study, the important law of permeability coefficient K is changing with the changing of depth, that is neglected, it impacts the water yield prediction of mine deposit. The error of water yield of mine deposit which is calculated by modified hydrogeological analogy method formula is smaller with big well method. So the hydrogeological analogy method which is suitable to this area can be built to predict the water yield of mine deposit.
