Based on the analysis of existing modern methods of prevention and control of endogenous fires and depleted coal stockpiles of coal spaces defines the main directions of development of processes to prevent spontaneous combustion of coal. In this paper we propose a method and a substantial and effective slowing down the process of spontaneous combustion of coal oxidized by atmospheric oxygen by reducing the initial temperature of the interacting components. To reduce the initial temperature of the mines proposed use of the evaporation of liquid, previously filed with the worked-out area of the mine. The implementation of the new approach in the prevention of spontaneous combustion of coal is carried out by periodic supply of spray in the air flow of liquid in the mining area to humidify the rocks in the mines . Lowering the temperature of coal is carried out by taking energy from the surface of the pre- moistened rock with intense evaporation of liquid from it at the expense of subsequent forced feeding of dry gas ( nitrogen ) into the mine. The data on the effect of cooling on its coal chemical activity. The effect of the process of spontaneous combustion of coal in the cluster .
