新庄煤矿保水采煤的环境影响及环境经济损益分析

Analysis of environmental influence and gain-and-lost in environment economy by application of the water-reserved coal extraction at Xinzhuang Mine

介绍了宁正矿区新庄煤矿可采煤层、含水层及隔水层的分布情况;从矿井生产安全、保护地下水资源、减少矿井水排放的角度综合考虑,提出保水采煤开采方案;分析了保水采煤方案对地下水环境的影响,并与原设计方案的环境效益及经济损失进行了对比。

Introduced is the distribution status of minable coal seams,water-bearing and water insulation strata at Xinzhuang Mine in Ningzheng Mine Region; with consideration on safety production,conservation of underground water resource and reduction of mine water effluence,an option of water-reserved coal extraction proposed; analyzed is the influence on underground water by this method and comparison taken with the originally designed option on environmental benefit and economic gain-and-lost.
