Abstract.

The investigation results of changes of the physical-mechanical and reservoir geomaterial properties of fluid saturation different degrees in the limit and beyond limit deformation area were given. The influence of strain speed on changing of the strength and deformation parameters of coals and rocks, depending on the type of fluid and the value of the lateral overpressure at different energy costs of destruction was established. The dependences of the compressibility on the parameters of pressure and fracture-pore space, as well as the dynamics of forming the degree of fluid saturation geomaterial were established. Control of destruction process was carried out by spectral seismoacoustics method with measuring of disintegration level by Fourier evaluation of amplitude-frequency and amplitude-time spectra.

Keywords: geomaterial, destruction, fluid, compressibility, form-changing energy, control
