摘　　要：基于新郑矿区以平均每年0．0813×10^8m。的涌水量向地表排放地下水，造成的地下水资源损失和地下水位持续下降的现实，在分析水文地质条件基础上，对比不同时期两张流场图特征，采用卡明斯基公式和弹性储存量公式，分别计算了矿山开采前和开采期间的不同类型地下水资源量，评价了矿山开采对地下水资源量的影响程度，为管理岩溶水资源和保护含水层起到关键的作用。As groundwater is discharging to surface in an average water inflow of 0.0813×10^8m^3 annually in Xinzheng mining area, groundwater resources is wasted and groundwater levels is continued declined. Based on analysis on hydrogeological conditions and comparing the features of two flow field maps at different periods, this paper calculates groundwater resources amount before and during the mining, evaluates the impact of mining on the groundwater resources by two different methods which are Kaminski and elastic storage capacity formulas. The proposals which protect karst water resources is put forward in this paper, which plays a guiding role for the program of geo-environment protection and recovery management at three coal mines.
