Abstract: In order to improve the detection effect of mine electric method on rock strata water-bearing, based on the electrode mode and data acquisition methods of traditional mine electric method, such as direct current method, electric perspective method and high-density electric method, and combined with the spatial potential distribution theory of full electric field, an innovative detection system with efficient combination of multi-core cable and matrix detection electrode was proposed. The results show that the electric prospecting of mine roadway, such as electric sounding, electric profile and electric perspective, can be completed by using this system in one round of wiring and power supply to improve the efficiency of underground geophysical exploration, enrich the variety of collected data, ensure the precision and reliability of hydrological geophysical exploration.
