【摘要】：神东矿区是我国重要的煤炭生产基地和典型的高强度开采矿区,同时也是我国典型的干旱半干旱生态环境脆弱区,矿区高强度煤炭生产与生态环境的协调发展是该区的重要研究课题。针对神东矿区干旱半干旱地区水资源贫乏、生态环境脆弱等特点,通过研究矿区水文地质结构特征、煤层覆岩结构类型等,提出了矿区的水文地质结构分区和保水采煤分区;以此为基础,针对不同的水文地质结构类型,提出了神东矿区的保水采煤的基本原则,以及矿区重要水源地、厚基岩含水层、烧变岩含水层、水资源转移存贮、矿井水资源化利用等保水采煤的关键技术;最后,结合典型矿井,开展了上述关键技术的现场工程实践,并取得了良好的应用效果。
[Abstract]:Shendong mining area is an important coal production base and a typical high-intensity mining area in China. It is also a typical arid and semi-arid ecological environment fragile area in China. The coordinated development of high-intensity coal production and ecological environment in mining area is an important research topic in this area. In view of the characteristics of water resources shortage and fragile ecological environment in arid and semi-arid area of Shendong mining area, the hydrogeological structure partition and water-retaining coal mining zone of mining area are put forward by studying the characteristics of hydrogeological structure and overburden structure of coal seam and so on. On the basis of this, in view of different types of hydrogeological structure, the basic principles of water conservation and coal mining in Shendong mining area are put forward, and the important water source, thick bedrock aquifer, burnt rock aquifer and water resources transfer storage in Shendong mining area are put forward. The key technology of coal mining with water conservation, such as the utilization of mine water resources; Finally, combined with typical mine, the field engineering practice of the key technology mentioned above has been carried out, and good application effect has been obtained.
