摘要: Abstract This paper addresses airflow stabilization in airways induced by outburst gas flows after the disappearance of shockwave. Based on fluid dynamics theory, a mathematical model an unsteady airway was established. The formation conditions additional force and ventilation pressure with their dynamic influences were investigated. results this study indicate that is created variation rate outbursts, hinders changes to maintains its original state motion. can be observed as increase potential energy coal outbursts. For upward ventilation, direction positive assists ventilation. However, for downward negative hindrance may lead reversal main airway.
