Numerical Simulation of Dividing Gob Spontaneous Combustion ＂Three Zones＂ by Double Index Method
Abstract：Fast and accurate division of gob spontaneous combustion ＂three zones＂ can provide an important reference for prevention and treatment of coal spontaneous combustion. Through the establishment of corresponding mathematical - physical model of gob flow field and the index analysis of dividing ＂three zones＂ , gob spontaneous combustion ＂three zones＂ can be divided fast by using numeri- cal simulation combining with double indexes method. By comparison validation with measured data, data results were in good agree- ment and the distribution of the gob spontaneous ＂three zones＂ can be divided accurately in earlier stage of working face forward.
