Two dimension numerical modeling of electrical penetrative detection in coal mine

It is indicated by researching the theory for electrical penetration between roads in the mine and its two dimension numerical modeling,and the case study that the technique of electrical penetration in the bed belongs to volume speculation.The detected effective depth is a depth interval.The different methods are of different properties,which appear abnormal properties of every target beds (in coal bed or surrounding beds).It would be useful for resolving the concrete problems of coal mining work face.
