蔚县矿区岩溶水供排结合研究

STUDY ON KARST SUPPLY AND KARST WATER DRAIN IN YUXIAN COAL MINING AREA, HEBEI PROVINCE

本文从系统观点出发,分析了矿区岩溶水供排结合的水文地质条件,提出了以供代排,合理的规划蔚县矿区地下水资源的供排结合方案。应用有限元数值模拟与最优化技术建立供排结合水量规划的教学模型,求出了蔚县矿区最佳水源地位置和最佳的供水开采量与疏干量,实现了较好的经济效益。

In the Karst region in North China, many mineral deposits gravely ravaged by Karst water, besides, Karst water bearing beds are the only water supplying resou-ces in mining area. Water draining and water supplying affect each other in a groundwater system.Thus,a balanced method of water draining and supplying is the best way to protect groundwater resources in Karst region.The paper analyzes systematically the hydrogeological condition and demonstrates a rational way of water draining and supplying.Response function is used in ground water simulation and an optimization model of exploitation is achieved. Finally, a ground water management scheme is presented.
