摘要
位于郑州市北郊黄河９５滩地的地下水源工程共钻井４６眼，日开采水量１０００００ｍ３。本文以区域地下水流方程模拟计算开采条件下的地下水位降深及等水位线，分析了工程对区域环境的影响，预测降深超过８ｍ的８３ｍ等水位线范围大于２２ｋｍ２。在此区域内，约有３８１眼农用机井将吊泵，失去抽水能力，年抽水量约４６１００００ｍ３。
The Yellow river beach underground water engineering is situated in the north suburban of Zheng Zhou, it will drilling 46 wells. Drilling extract water 100000m 3. The paper take localized area underground water engineering analogue calculate extract condition and underground contour water line would be dropping, analyse engineering given the district environment effect. Forecast contour water will be subsidence 8m to 83m, it gone beyound bounds contour water line over 22km 2. In the district about 381 agricultural wells drilling water will be losing. In the year drilling water about 4610000m 3.
