Abstract: In order to prevent coal and gas outburst disasters effectively and scientifically, based on the causes and occurrence rules of coal and gas outburst disasters, the diversified and precise technology structure for gas disaster prevention and control is put forward, which including "precise control of gas geology, gas drainageis reliable up to standard, intelligent early warning of gas emission and daily management norm of gas outburst prevention", a diversified precise gas disaster prevention and control system has been built from three aspects of equipment, model and software. The system realizes diversified and standardized prevention and control analysis and management of gas disasters.It can effectively improve the ability and level of mine gas disaster precise prevention and control technology, and the field application results are good.
