| Abstract: | Audio-frequency electric clairvoyance technology is one of the primary geophysical methods in coal mine water disaster prevention.Based on the primary principle of audio-frequency electric clairvoyance and the characteristic of seam floor partial abundance water influence on electric potential of point source field,abnormal water abundance regions in coal seam floor of Liudong Coal Mine,Huaibei Mining Group Company were detected,and electrical conductivity distribution characteristic and water abundance in different depth of strata were determined,which provides a basis for floor water control project design in coal mines. |
