本文通过J2—1井地下水位与大同二电厂井群开采降深的相关分析,揭示了它们之间的相关性。为进一步定量研究这种影响程度,用水动力学原理计算了电厂井群下降漏斗对J2—1井水位的理论干涉量。计算结果表明干涉量与J2—1井水位的实际下降量基本一致。认为J2—1井水位1985年的下降原因主要是二电厂井群大量开采所致。
In this paper, the correlation between the groundwater level in J2-1 well and the deep mining in Datong No.2 power plant is revealed, and the correlation between them is revealed. In order to quantitatively study the extent of this influence, the theoretical interference of the descending funnel of power plant group to J2-1 well water level was calculated by the principle of hydrodynamics. The calculation results show that the amount of interference is essentially the same as the actual drop of J2-1 well water level. It is believed that the reason for the decline of J2-1 well water level in 1985 is mainly due to the large-scale production of the second power plant well group.
