Laboratory researches of filter-capacity parameters of coal with due account of phase-physical condition and stress-strain state

Article preview

The Article contains the results of researches of dynamics in changes of physical and mechanical properties of enclosing sedimentary rocks and hard coals of the Kuzbass and Vorkutsk deposits. The general condition of change in permeability factor on gas was obtained, depending on forms and types of moisture bonds in rocks and intensity of stress state. In the research tasks necessary for solving the problem of methane extraction, the methodological aspects are a matter of interest to study the processes of sorption-desorption in natural gassaturated coals. Study of the sorption characteristics of coal has shown that its sorption capacity depends on the stage of metamorphism within the whole studied range of saturation pressures.
