煤矿水源地开采对延河泉泉水流量影响的预报

Prediction of the Influence Caused by the Coalpit Water Supply's Pumpage on the Yanhe Spring Discharge

:延河泉域上游已规划三个水源地 ,旨在为未来的煤炭开发提供水源。水源地的运行势必影响其下游的泉水流量。本文利用数学模型的调节反馈功能 ,通过将延河、下河泉区水位近似恒定做为约束条件 ,逐时段反复调试泉水流量进行水位拟合 ,较好地解决了延河泉域人工开采干扰泉水溢流量预报这一难题。

Three water supplies have been planned in upstream areas of Yanhe spring basin in order to provide water for exploiting coal in the future.The operation of these water supplies will surely influence on the spring discharge downstream.Taking advantage of the feedback-adjusting function of mathematic model, we adjusted the spring discharges on computer to fit the water levels of nodes in Yanhe、Xiahe spring areas step by step on the assumption that the node levels are invariable although they in fact have a little drawdown in the prediction, and eventually gained the influence that the operation of water supply in coalfield would exert on the springs.
