摘　　要：煤矿井工开采过程会引发一系列的地下水环境问题。为同时保护地下水环境和井工开采安全,以某煤矿2#煤层为研究案例,采用FLAC3D软件分析煤矿井工开采对顶板覆岩的影响机理,并以此为基础,从直罗组含水层和白垩系含水层2个角度综合分析煤矿井工开采对地下水环境的影响。此外,根据数值仿真模拟结果,介绍多种煤矿井工开采中地下水环境影响防范措施,旨在为后续煤矿井工开采中地下水环境问题的有效防范提供理论参考。The process of coal mine mining will cause a series of groundwater environmental problems.In order to protect the groundwater environment and the safety of underground mining,takes the No.2 coal seam of a coal mine as a research case,uses FLAC3D software to analyze the influence mechanism of coal mine underground mining on roof overburden,and comprehensively analyzes the impact of coal mine mining on groundwater environment from the perspectives of the Zhiluo formation aquifer and the Cretaceous aquifer.In addition,according to the numerical simulation results,a variety of preventive measures for groundwater environmental impact in coal mine mining are introduced,aiming to provide a theoretical reference for the effective prevention of groundwater environmental problems in subsequent coal mine mining.
