Abstract: At present, using modern equipment to forecast and predict is probing direction of self ignite point forecasting and predication in mine. From 1997, Hegang mining bureau put into computer monitoring system based on tube of flux at Junde coal mine, Nanshan coal mine, Xingshan coal mine, Dalu coal mine, Xing’an coal mine in seccession, which basically realized integrated and continuous monitoring for gas such as carbon mono xide in self ignite coal bed, mined out area, and burning section of each mine, and could forecast fire correctly and timely. It provide a realiable measure for early forecasting self ignite in mine.
