STUDT ON THERMAL INFRARED RADIATION TEMPERATURE OMEN IN COAL-MEASURE ROCK YIELDING UNDER GROUND PRESSURE

Through the monitoring the change of infrared radiation in 8-14μm wave band under rockuniaxial cyclic compression by ER-2007SAl type infrared thermometer. Three kinds of yield omens-radiation low-temperature omen, radiation low-temperature omen, radiation high-temperature ornen and continuous radiation high-temperature omen-have been discovered. According to entropy and energy conservationprinciples, the primary physical explanation is produced in this paper. The folow-up research directions ofmine pressure infrared detection and the prospects of mine pressure micro-wave remote sense detection arediscussed.
