Research on application of mine distributed laser fire monitoring system in Shanjiaoshu Mine
WANG Jun
Abstract：Underground fires have the characteristics of strong concealment and hazardous fire environment.Real-time monitoring and identifi-cation of underground fire hazards are of great significance for the safe and efficient production of coal mines.After identification,both the mineable and locally mineable coal seams in Shanshanshu Mine are spontaneous combustion coal seams,and the amount and technical diffi-culty of fire prevention and control engineering are high.In order to further improve the fire prevention and control capabilities of Shanshanshu Mine,KJ428 distributed laser fire monitoring system was used to monitor the basic parameters such as CO,temperature,O2,CH4,CO2,C2H4,C2H2,etc.in the goaf of the 221810 mining face in real-time.The monitoring data was basically consistent with the ground chromatographic a-nalysis values,within the allowable error range.This indicates that the KJ428 fire monitoring system has the characteristics of high sensitivity and fast response speed.The use of this equipment can further achieve real-time dynamic monitoring of the natural combustion status in the goaf and enclosed areas of the entire mine,early warning of fire risks,effectively avoiding or reducing the harm of fires to the mining environ-ment and personnel,and playing an important role in accurately dividing the"three zones"of goaf.
