摘要
The Jurassic coalfield at the energy and chemical base in northern Shaanxi is the first choice for the westward transfer of Chinese coal industry, and, as a result, the influence of coal mining on the groundwater resources and the ecological environment must be studied. Based on the hydrology and engineering geological condition, the authors classified the hydrogeological structure into seven types and the aquifer into five systems in the coalfield. The five aquifer systems can be further classified into several sub-systems according to the excretion datum. According to the studied results,the coalfield was finally classified into the hydraulic non-conductive district,and the hydraulic conductive district with no water, with a little water and with fluent water. The present and future strategies for coal mining were proposed from the view of water resources: coal mining with groundwater reserved, with both coal and groundwater exploitation and with recreation of aquifers.
