Numerical Simulation Study of Nitrogen Injection for Fire Prevention and parameter to confirm in Goaf

摘要：

This paper put forward the method of nitrogen injection and control nitrogen air to flow direction to utilize fugitive air to flow the aspect and controls air quantity in gob. It uses up wind finite element way to solved the seepage equation of the air movement and the seepage-dissipation-pervasion equation of the oxygen consumption density to change process in gob. According to the distribute regulation of nitrogen injection and the state of air flow field and oxygen distribution in goaf, it has been analyzed confirmed method of nitrogen injection quantity, position and time.
