Abstract：According to the problem that a large number of residual coal left in the goaf of the resources integration mine because of the early extensive mining,which was easy to cause spontaneous combustion of coal.Taking No. 4+9 coal seam of Beizu Coal Mine as a study subject,the combustion situation of fire area was researched through indicator gas experiment,and the high-temperature area of the roadway roof face was divided through infrared detection technique.The result showed that,CO、C2H4 and C2H6 could be taken as the indicator gas for spontaneous combustion in No. 4+9 coal seam of Beizu Coal Mine,the temperature in fire area was 80~110 ℃,and there was a tendency that the fire area enlarged from north to south.The research result provided reference for drilling detection and plugging and so on.
