Research on ‘Three Zones’ of Goaf Spontaneous Combustion with U+L Ventilation

Abstract:

In order to study “three zones” of goaf spontaneous combustion with U+L ventilation mode working face. Numerical simulation is used to simulate the distribution law of “three zones” of goaf spontaneous combustion in case of different distance between crossheading and working face, and different air quantity. Research suggests that the “three-zones” of spontaneous combustion has great influence with different distances and different supplied air volume.
