壳状渗透结构是裂隙岩体的渗透特征，主要表现是岩体的渗透率按负指数函数随深度衰减。在矿山开采深度范围内，渗透率可以减小几个数量级。本文根据壳状渗透结构下的矿坑涌水规律和地下水压力分布特征，探讨矿区城市地下水环境保护问题。
Shell-like infiltration structure is the infiltration characteristics of fractured rock mass, and the main manifestation is that the permeability of rock mass attenuates with depth according to a negative exponential function. Permeability can be reduced by several orders of magnitude over the mine depth. In this paper, based on the mine gushing under the shell-shaped infiltration structure and groundwater pressure distribution characteristics of the mining groundwater environmental protection problems.
