摘要

Majority of spontaneous combustion in coal mines are the results of air leakage in gob areas.It is an important means to find the rout of air leakage. According to the condition of west No.1 mining area in Linnancang coal mine, the potential energies around the fire zone were measured. The possible rout of air leakage was studied. The tracing -gas of SF6 was used and the rout of air leakage was found in the gob area. This practice provides sufficient assistance to the prevention and control of spontaneous combustion in gob areas and work safety in Linnancang coal mine.
