中文摘要	我国西部干旱-半干旱矿区既面临水资源匮乏,又面临矿井涌水量大、矿井水矿化度高等难题。为减少采煤过程中水资源浪费、保护西部地区水生态环境,基于保水采煤和煤-水双资源协调开采等理论基础与技术方法,围绕矿井水深部转移存储这一核心科学理念,提出将处理后的矿井水进行高压深井转移存储,转移至煤层底板深部含水层中存储。在鄂尔多斯盆地东部某矿实施试验井工程,通过开展野外岩样采集、室内电镜扫描、岩石成分分析、压汞等实验与定量-定性方法,研究目的转移存储层的水文地质条件和特征,分析不同高压水力压裂增渗试验主控因素,对比矿井水水质、转移存储层原生地层水水质和转移存储后混合水质,获取了矿井水高压持续深井转移存储的水文地质效应。结果表明:目前试验井单井累计转移存储矿井水量已满足设计预期,且持续高压水力压裂增渗方式可不断改善和渐次增强目的存储层的矿井水存储能力,延长服役时效。因此,高矿化度矿井水深部转移存储在技术和经济上具有可行性,将对西部地区水资源保护、水生态环境可持续发展产生重要意义;同时,相比高矿化度矿井水处理成本,能够有效缓解矿井水处理经济负担,为西部煤矿区矿井水转移存储提供典型示范。
英文摘要	In the arid and semi-arid regions of the Western China, there is not only a shortage of water resources, but also the problems of large mine water inflow and high salinity of mine water. In order to reduce the waste of water resources in the mining activities and protect water ecological environment in the region, it is proposed to treat the mine water by deeper well recharge to the aquifers under the coal seam based on the theories and technical methods such as mine water transfer and storage, water-preserving mining and coal-water dual resource coordinated mining. A test well project was implemented in a mine in the eastern part of the Ordos Basin. The storage space characteristics of the target recharge aquifers were studied by collecting rock samples, scanning electron microscopy, rock composition analysis and mercury intrusion experiments and quantitative and qualitative methods. Then, the main controlling factors of the in-situ water pressure tests were analyzed, and the quality of mine water and the water quality of the targeted recharge aquifer were compared. Finally the hydrogeological effect of mine water recharge was verified. The research results showed that the potential transport and storage capacity of a single well of the test well could meet a certain amount of mine water recharge demand. Transfer and storage cannot only improve the water richness of the targeted aquifers, but also have a significant impact on the protection of water resources and water ecological environment in the Western China. At the same time, it can reduce the cost of advanced mine water treatment, and relieve the environmental pressure of mine water discharge, which is a typical demonstration for transfer and storage of mine water in western coal mining area.
