本文对分别采用简单的解析法和较复杂的数值模型法计算露天采场地下涌水量的结果进行了比较。解析法假设的是流入贯穿理想承压含水层的全透水井（完整井）的横向流和径向流，而数值模型法模拟的是从有潜水面的含水层流入不完全透水井（非完整井）的全三维流．后一种方法是这一问题的较为理想的模拟，但是．前一种方法使用起来十分简便。用此两种方法按露天开采中遇到的某些代表性水文地质条件计算的结果经比较得出：两种结果的比值范围为0．2～0．6。这些数值可以用作露天采矿场水流解析法的一个系数，即使与此法应用中所包含的理想条件存在明显差异的情况下也可得出涌水量的合理预计值。
In this paper, the results of calculating the groundwater inflow in open pit by simple analytical method and more complicated numerical model respectively are compared. The analytical method assumes lateral and radial flow into a fully permeable well (intact well) that runs through an ideal confined aquifer, whereas numerical modeling simulates flow from an aquifer with a submerged surface into an impermeable well (incomplete Well) full three-dimensional flow. The latter method is a more ideal simulation of this problem, however. The former method is very easy to use. The results of these two methods, calculated on the basis of some representative hydrogeological conditions encountered in opencast mining, are compared: the ratio of the two results ranges from 0.2 to 0.6. These values can be used as a factor in surface flow analysis of open pit mining and a reasonable estimate of water gushing can be obtained even when there are significant differences from the ideal conditions contained in this application.
