    • Abstract
  • It takes a long time to withdraw caved face, and combustible coal seam tends to spontaneous combustion during the time, which threatens seriously the normal safety of coal mine production and brings huge economic losses to the coal mine. The situation of CO overrun exists during the withdrawal period and there are signs of spontaneous combustion in goaf of fully mechanized coal face in Shuntong Mine. Through the study of fire preventing and extinguishing technology during the withdrawal of fully mechanized coal face, it effectively controls the concentration of CO and prevents spontaneous combustion of float coal in goaf, and provides favorable conditions for the smooth withdrawal of caved face.
