Abstract: Research status of coalfield fire monitoring technologies was reviewed including electromagnetic detection method, resistivity method, radio wave method, geological radar method, gas measurement method, isotope radon measurement method, temperature method, remote sensing method and so on. Advantages and disadvantages of each technology were compared. It was pointed out that there were some questions existed in coalfield fire monitoring technologies at current such as lots of environmental factor limits, high cost, large technical limits and so on. Prospect of coalfield fire monitoring technology was taken out. It was pointed out that low altitude remote sensing technology of unmanned aerial vehicle equipped with an infrared thermal imager was development direction of coalfield fire monitoring technology. Moreover, development ideas were proposed which took high efficiency, intelligence and integration as leading role.
