Computer Simulation in Spontaneous-combustion Gob′s Air Flowing Field, Temperature Field and Heat-pressure Field

Zhang Ruilin Yang Yunliang Ma Zhelun (Jiaozuo Institute of Technology, Jiaozuo 454000) Zheng Lijun (Zhucun Coal Mine of Jiaozuo Mine Bureau)  
The theories of the conservation of mass and energy, porous-medium′s hydrokinetics, convection and conducting heat and ventilation and fire-prevention have been applied to the researches of computer simulation in spontaneocs-combustion gob′s air flowing, temperature and heat fields. Based on the building of the mathematics model of the gob′s unstable air flowing field, the temperrature field and the heat_pressure field by computing the heat_pressure field, a relation of the air flowing field to the temperature field is set up, then the programs to calculate the gob′s air flowing and the distribution of the temperature field, and the heat-pressure field have been analysed by the limited element method.
