Abstract
A simple fire source heat transfer model, on the basis of thermal equilibrium, was proposed. First, the differential equations that describe heat flow in ore body were presented and the relationship between the surface temperature distribution and the depth and intensity of inner fire source was established with a relatively simple heat transfer model. By the solution of the equation, the expression of the relationship between the surface temperature distribution and inner fire source was deduced and heat transfer process mathematical-physical model was set up. Then, with the model, visualization of fire source on the basis of MATLAB simulation platform was realized. It is possible to determine the depth of fire source and its intensity by locating method of fire source indirectly.
