The results of researches of mass transfer in a coal array and its conditions are described in the article. The influence of various physical processes on mass transfer is considered. An essential factor determining the direction of mass transfer in the coal array is the distribution of capillaries by classes. The physical effect for controlling mass transfer is directed at changing the structure of the capillary-porous space of coal. On the other hand, controlling of mass transfer is possible when the fluid properties change: contact angle of watering, coefficient of viscosity, coefficient of surface tension.
