前言地处东径86°57′—87°,北纬44°03′—44°08′,乌伊公路以南,东西宽约3公里,南北长约10公里,面积约30平方公里的白格达水源地(附图1)。设计机井30眼,年提水量3000万立方米。实际投入运转的机井25眼,年可采量2954万立方米。为验证水源地稳定持久开采的可能性,拟设使每一个机井都处在最佳流量开采状态下,整个水源地的地下水动态变化趋势、能否满足需水要求。为此,根据该地区的含水层特征、和现有的开采资料,选用了干扰井群法进行水文地质计算,其成果尚较理想,可供生产个门参考。
Foreword Located in the eastern diameter of 86 ° 57’-87 °, latitude 44 ° 03’-44 ° 08 ’, south of Wuyi Road, east-west width of 3 km, north-south about 10 km, an area of about 30 square kilometers of white grid Water source (Figure 1). Design 30 wells, the annual water volume of 30 million cubic meters. 25 wells actually put into operation, the annual recoverable volume 29540000 cubic meters. In order to verify the possibility of stable and long-term exploitation of water sources, it is proposed that each well be in the best state of flux exploitation and the dynamic trend of groundwater throughout the water source can meet the demand of water demand. Therefore, according to the characteristics of aquifers in the area and the existing mining data, the interference well group method was selected for hydrogeological calculation. The results are still satisfactory and can be used as a reference for the production.
