Abstract Coal spontaneous combustion is a commonly existed hazard in the coal field of the North China. Coal Fire Monitoring Information System(CFMIS) in Xinjiang, China was set up by applying the theory, technique and methods of geographicSystem (GIS). This system aims at guiding extinguishment of coal fires, providing information for making national fire fightting plans, monitoring the tendency and development of coal fires. Three classes CFMISs were established to meet the needs of administrative branches in different rank. This paper gives the general structure of these system and their hardware configuration and software composition. The models for extracting coal fire information from remote sensing imagery, calculating coal fire area, the losses of coal, the amount of released hazardous gas, the radianant temperature, the amount of released heat of coal fires and the expenses of extinguishment were developed. The characteristics and basic function of the system were presented.
