Division method of coal spontaneous combustion zone in multi-layer goafs based on fracture development law

In order to accurately divide the risk range of coal spontaneous combustion in multiple goafs of shallow buried deep coal seam group and take effective prevention and control measures, based on the porous medium seepage equation and oxygen volume fraction equilibrium equation, the mathematical model...
