摘要：
The temperature field of loose coal bulk was analytical calculated based on spherical heat source model. The relationship between the thermal exchange state of coal spontaneous combustion heat source and time was considered in mathematical model, so that the calculation results of temperature field was more in accordance with the fact. The experiment results of loose coal bulk temperature field show that the temperature of the feature points on physical boundaries and in loose coal bulk are differ in value, but are all within the range of the allowed tolerances and increase in the same trends, which implications that the analytical solution of the loose coal bulk temperature field is feasible.
