DISTRIBUTION OF TEMPERATURE IN DESTRUCTED COAL WITH A COURSE OF TIME

By underground mining of coal layers and storage of coal on a day surface there is a danger of self-ignition of coal owing to self-heating. The nature of formation of the center of spontaneous ignition is defined by properties of coal, in particular, coefficient of thermal diffusivity of coal. The coefficient of thermal diffusivity of coal depends on its physical and chemical properties: density of coal substance, extent of metamorphism, specific heat, etc. The decision allowing to define distribution of temperature over time in the destroyed coal depending on distance to the center of self-heating and speed of temperature change in the center is presented in article.

Keywords: COAL SELF-HEATING, COAL SELF-IGNITION, THERMAL DIFFUSIVITY OF COAL, COAL TEMPERATURE CHANGE.
