Abstract
The principle and interpretation method of the monopole-dipole DC penetration at working face are expounded briefly.The forward results indicate that both the vertical and parallel monopole-dipole methods can stress the influences of roof and floor rocks at working face, and suppress the influence of coal seam.It provides a new method to detect the water-bearing and water-flowing structures in roof and floor rocds at working face for the coal mine with large water yield.
