Abstract. Abstract. The results of experimental and theoretical studies relation energy transformation at the stage dispersion of the destroyed geo-environment are presented. The formation distributions on the sizes of the crushed particles are investigated taking into account physical bases fragmentation under loaded heterogeneous object. The use discrete-wave criterion of micro-destruction for the study evolution of the dispersing stage and estimation characteristics efficiency dispersion when a geo-environment is destroyed are substantiated. To enhance dispersive effects in the process of grinding geomaterials to use high-speed and high-frequency impulse loading mode is recommended. To study the kinetics transformation elastic energy into acoustic at the stage of under loading geo-environment samples, acoustic parameters are proposed. The parameters of energy transformation under loading and destruction series geomaterials by uniaxial and volumetric compression in the pressure range of 114-1720 MPa were experimentally determined. The importance information on the energy of dispersing at an over-extreme limit stage of deformation is registered.
Keywords: Keywords: geological environment, energy destruction, dispersion effects.
