Abstract: In order to find out water abundance and development distribution situation of water conducted structure within the scope of the+10 roadway ahead 80 meters, based on the analysis of geophysics premise such as elasticity and the electric magnetic differences, combined with the actual production data of roadway, designed optimal observation system, the seismic probing MSP and transient electromagnetic method are used to advanced detection of +10 roadway. The results show that there is no obvious water conducted structure within the detection area, no significant water abundance abnormal phenomenon, it tallies with the actual mining data, the effect is better, prove that the selected detection technology is more reasonable.
