Direct current method for bed-parallel advanced detection of water bearing structure in mine tunnel

The invention discloses a direct current method for bed-parallel advanced detection of water bearing structure in mine tunnel. Common advanced detection technology comprises a seismic reflection wave method, a Rayleigh wave method and the like, but with the extensive application of a fully-mechanized roadheader, the above methods are harder to adapt to the present production task requirements. The method of the invention is as follows: a mine direct current method seven-electrode series detecting device is used to arrange four current-emitting electrodes of A1, A2, A3 and A4 which are arranged on one straight line near a mine tunnel heading end, and the four current-emitting electrodes respectively form a loop with another current-emitting electrode B arranged at infinity to supply direct current under the ground, so that a direct current field is built; meanwhile, two electrodes M and N with relatively fixed distance behind the tunnel are used for measuring the distribution rule of the electric field; after treatment with special mating interpreting technology, electrical property distribution information in a geologic body 0-140m ahead a drifting tunnel or a tunnel is obtained. The invention has the advantages of small workload, high speed, small possibility of influence by personal factors, high objectivity and high accuracy, and belongs to a non-destructive detection method.
