【摘要】：围绕西北煤炭开采中水资源保护基础理论研究中的关键科学问题,介绍了西北煤田地层结构特征、采动覆岩结构与隔水层稳定性时空演变规律和水资源保护性采煤机理与控制理论等方面的研究进展情况。构建了西北矿区不同生态地质环境类型生态-水-煤系地层空间赋存结构模型,分析了浅表层水分布特征与水循环运移规律;提出了覆岩裂隙表述和重构方法,构建了上位隔水层-中位阻隔层-下位基本顶结构协同变化模型和渐序变化模型;构建了该区初/复采煤层保水开采技术适用性分类方法体系,探索了新式短壁保水采煤方法,为构建基于水资源保护的西北煤炭科学开采方法体系奠定基础。
[Abstract]:Focusing on the key scientific problems in the basic theory of water resources protection in northwest coal mining, the stratigraphic structure characteristics of northwest coal field are introduced. The research progress on the space-time evolution law of mining overburden structure and the stability of water-proof stratum and the theory of water resources protected coal mining mechanism and control. In this paper, a spatial structure model of ecological-water-coal measure strata of different types of eco-geological environment in northwest mining area is constructed, the distribution characteristics of shallow surface water and the law of water circulation migration are analyzed, and the method of describing and reconstructing overburden fractures is put forward. The cooperative change model and gradual sequence change model of upper layer, middle barrier layer and lower basic roof structure are constructed, and the classification system of applicability of water-retaining mining technology in primary / complex mining coal seam in this area is constructed, and a new type of short-wall water-retaining coal mining method is explored. It lays a foundation for constructing the scientific mining method system of northwest coal based on water resources protection.
