Abstract
By pre-burying beam tube and thermocouples in 14128 fully mechanized mining face,the paper measured the distribution and variation of oxygen concentration,oxidizing output and losing coal temperature with the advance of face,ensured the width of three band of coal spontaneous combustion in gob.
