Study on "three zones" distribution of gob coal spontaneous combustion in Xiashijie mine

Hua Feng

Abstract

By field observation on fully mechanized caving face in Xiashijie mine,the distribution of loose coal thickness and oxygen concentration in the gob is determined.Based on spontaneous combustion three partitioning theory,the distribution of three and spontaneous combustion danger zones in the gob is determined which can provide basis for prevention of coal spontaneous combustion.
