Abstract: In this paper, taking 7^#, 8^# coal seam in a western mine as the background, theoretical analysis, numerical simulation and field practice are used to study spontaneous combustion control problem of composite goaf in shallow buried depth close coal seam. The results show that the part of composite goaf spontaneous combustion "three zones" in close horizontal direction is larger than 150 m away from working face, oxygen concentration increases in goaf near gob-side entry retaining; the area of coal oxidation time is long, and the spontaneous combustion risk is higher; in the vertical direction, the oxygen concentration is low, and the "three zones" range is smaller.
