Abstract
Being based on the geology and distribution of spontaneous thick seam island 21072 working face, analyzed the relationship between the spontaneous combustion danger factors of the isolated working face and the old roadway, the high temperature coal over the roadway roof, the temperature of the working face, the continuous supply of oxygen for goaf, by eliminating the high temperature coal to reduce oxygen content, laying pipe in the corner of working face ofifce for grouting to the goaf, laying striped cloth in top of support and stop mining goaf , plugging the air leakage channel during working face end-mining, wetting the lfoat coal in goaf, injecting the nitrogen to goaf, and using three-phase foam, effectively put an end to the production and removal at the end of the period of coal spontaneous combustion.关键词
