The methods for selecting parameters of elastic elements vibrating machines, calculating the characteristics of stiffness and damping of elastic elements vibrating machines, calculation of dynamic characteristics of elastic elements with regard to their nonlinearity, prediction of durability of elastic elements taking into account the effects of radiation. The influence of rock samples metasomatic alteration of granite Vatutinsky deposits of uranium ores of high power electric discharge on the character, the spatial distribution and intensity of the newly formed microcracks. The features of classification and dewatering fine granular media at polyfrequency mode dynamic loading, studied the effect of energy-power parameters of the processes of fine granular media classification and dewatering of fine granular media. For the first time in the laboratory used the idea of rock pressure control by changing the pressure in the hydraulic cylinders mechanized longwall mounts on a predetermined algorithm that is presented in the patent of Ukraine №89965 od 06.02.2014, which allowed the development of a method of modeling of stationary and dynamic loading of the rock in a gaseous environment for determining the change in its physical and mechanical characteristics. A mathematical model of the flow of processes related changes of stress state of rock mass under the weight of the overlying rocks are concentrated in the explosion of charges and non-stationary, non-linear filtering of gaseous detonation products. In terms of testing elements of geomechanical monitoring performed instrumental and visual inspection, as well as vibroacoustic diagnosis of a number of mining shafts "new" and mine ventilation shaft "Operational". According to the results of surveys prepared conclusions about the state of marginal zone geomechanical workings and trunk lining, as well as recommendations for their maintenance. The economic effect was, respectively, 520 thousand. UAH. and 8.2 million. UAH. Product Description popup.authors Єфремов Е.І. Булат А.Ф. Дирда В.І. Скіпочка С.І. Шевченко В.Г.
