摘　　要：为了探究煤矿开采对周边水资源环境造成的影响,以和成煤矿为研究对象,结合矿山给排水系统、废污水处理及回用情况,论述了区域水文地质条件,边界范围,岩溶水补、径、排条件,水资源开发利用现状和水资源影响因素,通过标准指数法、经验公式和重点监测断面采样监测等方法,开展对该矿山运行期对地表水水环境、煤系及煤系上覆含水层、下伏含水层以及断层和陷落柱的影响分析。结果表明,矿山正常工况条件下退水不易对周边地表水造成影响,项目开采煤层不易对周边水库及大坝产生明显的影响,开采不会破坏浅部含水层、煤系地层及砂岩含水层、下伏含水层产生破坏,亦不会产生岩溶水突水危险。但在矿山建设期间应加强该方面监测。In order to investigate the impact of coal mining on the surrounding water resources environment,taking Hecheng coal mine as the research object,combined with the mine water supply and drainage system,wastewater treatment and reuse,discussing the regional hydro-geological conditions,the boundary range,the conditions of karst water replenishment,runoff and discharge,the current situation of water resources development and utilization and water resources influencing factors,and through the method of standard index method,empirical formulas,and the key monitoring cross-section sampling monitoring and so on,to carry out the assessment of the surface water environment,the coal system,and the coal mine during the operation period.Through the standard index method,empirical formula and sampling and monitoring of key monitoring sections,the impact analysis of the mine on the surface water environment,coal system,overlying aquifer,underlying aquifer,faults and trap columns during the operation period was carried out.The results show that the mine will not easily affect the surrounding surface water under normal working conditions,and the coal seams mined under the project will not easily affect the surrounding reservoirs and dams,and the mining will not damage the shallow aquifers,coal and sandstone aquifers,and the underlying aquifers,nor will it create the danger of karst water outbursts.However,the monitoring of this aspect should be strengthened during the construction of the mine.
