Research on vertical air leakage law of surface in goaf of shallow coal seams under different seasonal conditions

Under the influence of mining, the overlying strata of shallow coal seam fully mechanized top coal caving face collapses and forms cracks that connect with the surface. The vertical air leakage caused by these cracks has a significant impact on the spontaneous combustion of coal in the goaf. In orde...
