Abstract

In view of the existing problems in the coal sample collection method of the coal seam gas content, a sampling method of fast sealing and sampling in coal seam drilling is proposed and the method's control signal can achieve the non-contact transmission by electromagnetic induction principle. The equivalent model of the electromagnetic induction transmission circuit is given, and the related laboratory experiments are carried out to verify the feasibility of the non-contact signal transmission. A series of conclusions are obtained: the sum of the voltages on the ideal state of all couplers is constant, and the voltage on each coupler is equal; the induced voltage is more stable when the transmission frequency is 240~310kHz; increasing the number of coils' turns will improve the transmission efficiency, but it also increase the copper loss, so the most appropriate turns are around 40T; enlarging the coil gap will reduce the transmission efficiency, so the coil's gap should be reduced.
