摘要：Spontaneous combustion of mine rock dump (coal gangue pile) has posed a constant threat to the safety of mine areas by polluting its atmosphere, water, soil and even the threat of unpredictable explosion. Traditional monitoring techniques like utilizing thermocouples and thermometers can only measure the surface temperature on a point-by-point basis and hence are costly and time-consuming. Infrared thermograph, compared with the traditional techniques, has the greater coverage area and higher precision temperature results. But, for lacking of spatial information in the thermo-image, it is proposed to integrate GPS and infrared thermograph to monitor spontaneous combustion of mine rock dump. Some key issues including principles of setting control net, the method of mining spatial coordinates from thermo-image and data processing steps are investigated in detail. Finally, the capability of infrared thermography for its application in monitoring and early warning the spontaneous combustion of mine rock dump is emphasized
