摘要： The present disclosure includes a method of testing for gas and temperature distribution in a goaf, wherein the test device comprises a cable coupled to a cable dragging machine, the cable including a test end configured to be buried in the goaf; a gas temperature tester configured to test a gas for composition and temperature; and a gas pump configured to continuously pump gas from the test end and transmit it to the gas temperature tester. In some examples, the method comprises placing the test end of the cable in the goaf. According to some examples, the method comprises starting the cable dragging machine and starting the gas pump simultaneously with starting the cable dragging machine. The method may comprise withdrawing the cable, via the cable dragging machine, at a constant speed and analyzing, via the gas temperature tester, the composition and temperature of the gas.

摘要： The present disclosure includes a test device for gas and temperature distribution in a goaf, comprising a gas temperature tester configured to analyze gas detection signals and temperature detection signals. In some examples, the test device comprises a gas pump coupled to the gas temperature tester and a connector coupled to the gas pump at an end opposite the gas temperature tester. The test device may comprise a wire spool rotatably coupled to the connector and a cable configured to wind on the wire spool. According to some examples, the cable comprises a test end located on a first end of the wire spool and buried in the goaf. The cable may comprise an output end located on a second end of the wire spool, the second end opposite the first end.
