焦作矿区裂隙岩溶水优势流形成机理研究
|
摘要
本文根据优势面分析原理对焦作矿区裂隙岩溶水优势流形成机理进行了比较系统地研究 ,分析了优势结构面控水特征和规律。抽水试验实例以及数值模拟结果均表明裂隙岩溶水运动存在优势流 ,利用综合优势判断裂隙岩溶水优势流方法实用、可行。结论对于基岩矿坑涌水量数值计算或用数值法进行裂隙岩溶水资源评价时参数正确分区具有重要的参考价值
According to the theory for preferred plane analysis,the mechanism of preferential flow in the media of fractured karst in Jiaozuo Mine is studied.The characteristics and rule of flow controlled by the preferred plane are found.Example of pumping test as well as the result of modeling show that the preferential flow exists and the preferential flow can be simply judged based on several factors on the preferred plane.It is useful for flow modeling and evaluation of ground water resources in fractured karst area.
