摘要

摘要: 我国西北干旱半干旱地区水资源总体贫乏，但煤炭储量丰富，且埋藏浅。煤炭开采覆岩土破裂常发育到地表，破坏浅表层水资源，造成潜水水位下降、地表水枯竭，生态地质环境恶化，实施水资源保护性开采(保水采煤)是西北干旱地区煤炭科学开采的唯一选择。本文叙述了保水采煤的历史和现状，分析了采空区储水的基本条件和机理，给出了采空区储水的水量预计方法，并以实例说明了采空区储水水量和水质效果，认为采空区储水是西北干旱区浅埋煤层大规模保水开采的最有效途径。

Abstract: The coal resources in semiarid-arid northwestern China are charactered with rich reserves, shallow buried, but short water source. The water fracture zone of overburden rock due to coal mining could develop to the surface, destroying the shallow water resources, causing the loss of phreatic water, drying up the surface water, and deteriorating the ecological and geological environment. Therefore, the implementation of water resources protective exploitation(water preserved mining) is the only choice for the coal mining in northwestern China. This paper discussed the history and status of water preserved mining,analyzed the basic condition and mechanism of goaf water storage, yielded the predicting approach for the amount of goaf water, showed the quantity and quality of goaf water with an example, and suggested that the goaf water storage is the most effective way for the shallow buried coal mining in the northwestern arid areas of China.
