摘　　要：陕北侏罗纪煤田煤层埋藏浅,地表生态环境脆弱,煤炭开采过程中的环境保护备受关注。目前重点开发的神北矿区和榆神矿区东部,煤层埋深普遍小于150m,开采导致水位下降,诱发一系列表生生态环境问题和社会矛盾。表生生态环境严格受控于地下水位,采煤过程中,控制地下水位不发生明显下降是陕北生态脆弱矿区保水开采的核心。榆神矿区含煤地层整体向北西倾斜,煤层上覆基岩厚度向北西方向增大,基岩之上普遍分布有红土隔水层,深入研究煤炭开采过程中不对含水层造成破坏的煤水共生地质条件,确定既可采煤、又可实现水位不明显下降的区域,是陕北生态脆弱矿区保水开采的重要途径。论述了榆神矿区西部区保水开采地质条件,提出了开发建议。Jurassic coalfield in North Shaanxi is of the shallow-buried coal seam, fragile surface ecological environment and concerning environment protection during the coal mining process. In the Shenbei mining area and eastern Yushen mining area, coal seams are less than 150m below the surface. The mining leads to decline of water table, resulting in a series of the ecological environmental and social problems. Due to the surface ecological environment is controlled by the water table, so to protect the water table from obvious decline is a core task for the water-conserving mining in the fragile ecological mine area. Coal-bearing seams in Shenyu mine area inclines northwest, the bedrock thickness on the coal seams increases northwest, and there are generally red soil water-resisting layer on the bedrock. To study on the coal-water friendly geological conditions for the water-resisting layer during the coal mining process, and to determine mining zones without causing obvious water table decline are an important approach to the water-conserving mining in the fragile ecological mine area of North Shaanxi. The waterconserving mining geological condition for Yushen mine area is elaborated, and several development suggestions are put forward.
