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

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.

A new technique for the determination of ultimate strength in extention of rocks

A new technique has been developed for the determination of ultimate strength in uniaxial extension by testing results of samples of arbitrary shape. This technique consists in the sample failure with spherical indentors and measuring of sizes of rupture surfaces and zones of failured rocks at contacts with indentors for the subsequent estimation of ultimate stress state. The revised formulas were obtained for calculation of ultimate strength in uniaxial extension with using the method of sample failure with spherical indentors, essentially improving the accuracy of the technique.

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

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

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.

Determination of indices of strength certificate оf rocks using the method of specimens failure with spherical indentors

The method has been developed for the determination of indices of strength certificate of rocks using the technique of specimen’s failure with oncoming spherical indentors. This method is based on the assessment of ultimate stresses acting in the tensile plane and within the zones of failured rocks under action of indentors at the moment of sample splitting. Formulas were obtained for calculation of indices of strength certificate, i.e. cohesion and angles of internal friction under tensile compression and nonuniform triaxial compression, ultimate strength in uniaxial compression and tension. This method is applicable in situ conditions.

Application of solid oxygen-containing substances for higher productivity of oil wells

The technological principles and results of realization of exothermal reactions in oil-and-gas productive wells are presented. Unique comfinations of chemical reagents on base of chlorates, saltpetres, etc ensured the simplicity, low prices and efficiency of technological operations for intensive influxes of oil and gas. High efficiency is reached not only due to reduction of oil viscosity and removal of paraffin and asphaltenes, but also due to re-forming of the reservoir rocks by relief of rock pressure and extension of fractures.
