In recent years, the frequency and intensity of spontaneous combustion of coal in Australian underground coal mines has shown worrying signs of increasing. To enhance spontaneous combustion management capabilities in the Australian coal industry, a study was undertaken to investigate three innovative techniques that have been successfully used in China. These three are the radon detection technique, the infrared technique and the colloid injection technique. The radon detection technique is for remotely locating the areas of underground spontaneous combustion from a surface location. The infrared detection technique is for locating the spontaneous combustion within a short distance. The colloids injection technique is for controlling spontaneous combustion after it is located. This paper describes these techniques including their principles, operations, applications in China, and applicability in Australia.
