Abstract:Spontaneous combustion of coal constitutes a very serious problem in North China. Practice proves that the application of remote sensing technology can achieve rapid dynamic monitoring of coal fire and provide information for the fire-extinguishing project, thus exhibiting great significance. Burnt rocks as the indicators of coal fire at the earth's surface serve as the most visual information for interpreting coal fire. Based on the reflectance curve characteristics of burnt rocks, the authors compared various methods for extracting the information of burnt rocks, and then determined the best method for this purpose, which can help locate and delineate the coal fire.
