【Abstract】 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.更多还原
