【摘要】：针对神东矿区矿井水外排蒸发损失的问题,分析了以往保水采煤方法的不足,系统研究了矿区水文地质条件,提出了矿区三类水(近地表土壤水、第四系松散层孔隙水和基岩裂隙水)概念。在此基础上,神东矿区通过开展一系列水资源保护和利用技术研究,掌握了矿区煤炭现代开采地下水的运移规律,相继研发了采空区储水设施、煤矿地下水库和煤矿分布式地下水库的水资源保护和利用技术,形成了以煤矿地下水库为核心的矿区水资源保护和利用技术,并通过技术提升,建成了大柳塔矿分布式地下水库示范工程,实现了矿井水井下循环利用。现场工程应用表明,神东矿区煤矿地下水库安全稳定运行,提供了矿区95%以上用水,有效保障了矿区的可持续发展,为我国西部地区煤炭开采水资源保护利用技开辟了新的技术途径。
[Abstract]:In view of the mine water efflux evaporation loss in Shendong mining area, analyzes the shortcomings of previous water preserving mining method, studied the hydrogeological conditions of the mine, the mine three types of water (near surface soil water, Quaternary pore water and bedrock fissure water). On this basis, through a series of Shendong Mining Area water resources protection and utilization of technology research, mastered the migration law of coal mining modern exploitation of groundwater, have developed goaf water storage facilities, underground reservoirs and coal mine distributed underground reservoir water resources protection and utilization technology, formed the core of mining coal mine underground reservoir water resources protection and utilization technology, and through improving technology, built underground reservoir in Daliuta coal mine distributed demonstration project, the underground mine water recycling. The engineering application in Shendong mining area of coal mine underground water security The fully stable operation provided more than 95% water for the mining area, effectively ensured the sustainable development of the mining area, and opened up a new technological way for the protection and utilization technology of water resources in the coal mining area of Western China.

【正文快照】： 煤炭是我国的主体能源,占我国一次能源生产和消费的70%左右,且在未来相当长时期内,煤炭为主体能源的结构不会改变。西部是我国煤炭的主产区,但地处干旱半干旱区域,干旱缺水,且蒸发量大,年蒸发量为降雨量的6倍左右。由于煤炭开采对上覆岩层的影响,形成的裂隙导通含水层,含水层
