摘要

Studied on multi-component combustible gas,methane mainly,explosion characteristics of high gas mine,obtained the rules of gas explosive limit that influenced by environment temperature,pressure,concentration of oxygen,other combustible gas,coaldust,energy of fire source,and the inert gas,proposed a new method of divide gas explosive tdangle partition,and gave new partition linear equations.The gas explosive triangle and its new partition has important directive significance in distinguishing if the fire area has a gas explosion when sealing or opening fire area,or fire extinguishing in sealed firearea,and judging if there will be a gas explosion or other trend while fire extinguishing with inert gas.
