The regularities of the development of the frequency and amplitude of self-oscillations from the pressure of the liquid head in the well at the stages of initiation, periodically steady-shear flow and its attenuation, which will allow to justify the working range of the device for hydro pulse action for different depths of occurrence of coal seams. Based on the assessment of structural transformation of the coal substance in the gasification process carried out in laboratoryscale coal petrographic methods, it is established that the gasification process during metamorphism of coal creates in the structure of coal substance additional cavities, which are identified by petrographic methods. The dimensions of the gas generation allow the gas to be in such cavities in the free state. The peculiarities of the mechanism of occurrence of gas-dynamic phenomena that are the cause of their occurrence can serve as the ratio of compressive and tensile stresses in the array. The magnitude of the elastic and inelastic characteristics that develop in the array, can be controlled by adjusting the concentration of the chemical components in the composition, which is blown, changing, thereby, the concentration of the solution, or by changing the composition, giving him invigorating properties, which further increases the homogeneity of the structure of coal and surrounding rocks, eventually eliminating the gradient of physical-mechanical properties of the array, but the magnitude of limit stresses remains unchanged or decreases. Built regression models to determine the performance of crushers, such as jaw on the size of the discharge gap and roll from six significant figures. Analytical dependences of the distribution of yield, content and recovery of copper by classes of size of the fragmentation products. The resulting dependence of the efficiency of vibrating screen from six design and operating parameters and rock properties (density). The resulting dependence of the screening performance on the angle of inclination of the forced vibration exciter with other parameters fixed at the level of the rational. The developed model stress-strain state armorology membranes, which allowed to establish the regularities and peculiarities of the change of stresses and deformations of reinforced armoredge contour generation under the influence of rock pressure. Define the mode of maintaining the set level of the load in the accumulating hopper in which a simple down-hole equipment is minimal. For the first time for geotechnological systems solves the problem of management of process of preparation of structured suspensions, which ensures existing pumps through existing pipelines to reliably deliver to the consumer a solid material in the required quantity. For the first time proved the value of slurry concentration, the value of which provides the coincidence of the operating point considered hydrotransport system regulated feed that allows you to calculate required for the successful hydrotransportation values of rheological characteristics. The analysis of management options options underground facilities for hydrotransport by changing the parameters of the pipeline, pump unit, and due to the volume of water and rock mass. For facilities for hydrotransport formulated and solved the problem of regulation, which is based on the control of particle size distribution of the transported material, and the ratio of the cost of water flowing into the sump and on the jetting.
