Tensor Impedance CSAMT Launch System ——TXM-22
At present, the general CSAMT transmitter can only inject square wave, sine wave or triangular wave currents with different frequencies into the ground through a single electric dipole, and the artificial electromagnetic field generated by it is a single polarization field with the same phase, so it can only calculate the scalar impedance value of the ground, which is only suitable for detecting simple, horizontally layered one-dimensional structures, and its observable area is in the sector area of 120 with the center of the electric dipole as the vertex. The German company Metronix recently developed the tensor impedance CSAMT transmission system TXM-22. The transmitter TXM-22 can simultaneously send transmission currents with different polarities and intensities to the three grounding electrodes U, V and W at a given frequency, so as to establish synthetic current vectors and polarized magnetic fields in different directions underground, so that the best electromagnetic field signals can be observed in the whole range around the electrodes, greatly increasing the observation area and accuracy; At a given frequency, four tensor impedance element values of 15 group can be solved, and the best group is selected to participate in the calculation of parameters such as apparent resistivity and phase curve, which significantly improves the calculation quality of tensor impedance. It is suitable for target detection under complex geological structure conditions.

Underground explosion-proof trough wave seismograph Summit Ⅱ (EX)
Summit II (EX) is an underground explosion-proof slot wave seismograph developed and produced by German DMT company. It is the third generation product and the most advanced underground explosion-proof seismic system in the world. At present, it has been effectively applied in many coal mines in the world. Only from 20 10 to 20 12, six domestic coal mining groups purchased Summit II (EX) explosion-proof trough wave seismograph.
Slot wave is a kind of dispersive seismic wave. Because the wave velocity of coal seam is obviously lower than that of roof and floor, the groove wave excited in coal seam only propagates along coal seam, carrying all kinds of abnormal information in coal seam. Underground trough wave seismic exploration can determine geological problems such as large and small faults, collapse columns, changes in coal seam thickness, distribution of gangue inclusions, coal seam erosion and pinch-out, and judge disaster areas such as old kiln, high pressure zone and gas enrichment zone in coal seam. Slot wave seismic exploration can be divided into transmission exploration and reflection exploration. The exploration distance of transmission method is 300 times of coal thickness, and that of reflection method is 100 times of coal seam.
