Abstract：
From researching the electrical penetration field theory between two roads of panel and it's one dimension numerical modeling,it is indicated that six electrical penetration techniques have obvious reflection to the change of electrical characters in roof and floor of the panel,but less reflection to the coal seam itself.The research provides the theory basis for detecting water bearing and water conductive structures in the roof or floor of panels.
Key Words： mine electrical penetration methods;one dimensional forward solution;numerical simulation
