Problems solved by technology
Due to the influence of the volume effect of the direct current method, the vertical and lateral resolutions of the ground direct current method gradually decrease with the increase of the detection depth, and the detection depth is limited (generally less than 200m), which is difficult to meet the high-resolution detection requirements of deep mines
Due to the intrinsic safety and explosion-proof requirements of mine equipment, the general power supply current is not greater than 100mA, the detection distance is small (generally not greater than 100m), the signal-to-noise ratio of data is low, and the detection reliability is poor. Therefore, it is difficult to carry out underground DC detection.
[0003] To sum up, at present, in coal mine exploration operations, the direct current method has not yet fully exerted its value in geological exploration.

Description
technical field [0001] The invention relates to a detection system based on the data acquisition of the three-dimensional direct current method in the upper and lower wells. Background technique [0002] At present, the detection technology and equipment of hidden disaster-causing geological factors in coal mines are mostly based on ground detection. The direct current method used in the field of coal mine exploration mainly includes the ground direct current method. Due to the influence of the volume effect of the direct current method, the vertical and lateral resolutions of the surface direct current method gradually decrease with the increase of the detection depth, and the detection depth is limited (generally less than 200m), which makes it difficult to meet the high-resolution detection requirements of deep mines. Due to the intrinsic safety and explosion-proof requirements of mine equipment, the general power supply current is not greater than 100mA, the detection d...
