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.

Qiuck-acting technique for the determination of rheological properties of rocks

Article preview

The Article considers the rheological tests of rock samples being carried out with using the direct (classical) and quick-acting (stepwise) techniques. In the stepwise test of one sample a family of creeping curves was obtained. The comparable tests have shown a satisfactory similarity of test results obtained in various testing techniques.

Influence of rock disturbance on their rheological properties

Article preview

Complex investigations have been conducted of rheological properties of undisturbed and disturbed rocks under laboratory conditions in the modes of creeping, relaxation and lateral pressure. It was stated that the rheological properties of disturbed rocks substantially differ from those properties of undisturbed rocks. Recommendations are given for the use of the obtained results in solution of tasks in mining geomechanics.
