The Use of Beam Tube Monitoring and Measuring System in the Study on Spontaneous Combustion

Every coal seam of Linnancang coal mine belongs to the spontaneous combustion coal seam.The use of top caving mining method left much coal in the gob area.Because there are multi air leakage channels,spontaneous combustion is ofen occurred.In order to strengthen fireproofing management and understand the natural oxidation of the gob area,the beam tube monitoring and measuring system was used to observe the air contents of 1226 working face.The spontaneous combustion rule in gob area was gotten.·It can be used to guide the production of Linnancang coal mine.
