INCLINATION OF COALS TO LOW-TEMPERATURE OXIDATION AND MONITORING ENDOGENOUS FIRE DANGER
It's proved that by oxidation of coals for temperature 60 - 100 °C arising small quantity of gas subjects and main mass of fixed oxygen react coal subject irreversibly. Low-temperature oxidation process can be produced as succession of follow macro-kinetics of physical-chemical reactions: transfer of oxygen to sorption coal values by filtration or diffusion on cracks and macropores; diffusion transfer of oxygen to reaction surface of coal pores; physical-chemical interacting oxygen with coal and heat-transfer process. Thus calculation experiment with using information about inclination of coals to low-temperature oxidation allows determining fare safety conditions of mining.
