Experimental Study on the Radon Migration in Coal Spontaneous Combustion

The traditional radon migration theory is mainly diffusion advection, pore fluid, stress strain, transfer behavior, temperature and pressure. Through the simulation of the process of coal oxidation, detection of the main gases produced from the process, and correlation analysis of the gas data, we have proved that 'geogas' theory has explained the relationship between radon and fire gases goodly, and the theory's applicability is proved feasible in this process. It is very important for the research on the technology of fire detection by radon.
