Abstract: Based on the general theory Spontaneous Conbustion of coal, combining with specific situation about irregular coal working face of XINAN, design the specific Monitoring Scheme of three-zone,the paper use numerical fitting predict the distribution of three-zone according to the previous segmental measured data. In the anaphase mining, measured the distribution range of three zone, choose a point for data analysis of SPSS, the results of the analysis and prediction range high similarity. Finally, determine the distribution law of three-zone: heat release 0~12m, oxidization temperature rise 12~27m and asphyxiation above 27m.

Key words: Three-zone, spontaneous conbustion, range of oxygen concentration, numerical fitting
