“…Instrumental methods for studying the structural and physical-technical characteristics of technogenic rock massifs consisting of relatively large pieces of rock are in most cases inapplicable due to their high cost. In this regard, there is a need to turn to mathematical models of granular media [1][2][3][4][5][6][11][12][13][14][15][16][17][18][19][20].…”

The paper describes a method for determining the density and specific surface of the package of rock particles represented by discs with the size corresponding to the size of the rock fragments of real dump massifs (2D case). The packing method of the particles corresponds to the schemes of dumping used in open-pit mining - areal and peripheral ones. The influence of boundaries, in which the dump is located, on the physical characteristics of this massif - density and porosity - is revealed. It was revealed that the way of formation of the bulk of particles affects its density, especially at the boundaries of the massif. The massif of particles formed in accordance with the area technology of dumping has a denser composition and is less affected by the effect of its boundaries than the massif formed in accordance with the peripheral technology of dumping. The applied method of determining the physical characteristics of the bulk medium differs from the statistical methods (e.g., Monte Carlo) and is well-proven for static media, such as dumps and filtering massifs in open-pit mining.

“…Based on the mining conditions of driving mine workings by the geokhod with the blade CB presented in Table 1 and the expressions used in works [15][16][17], the full projection of the soil cutting resistance force on the axis of rotation of the geokhod and the plane perpendicular to the axis of rotation were calculated as well as the total moment of resistance to cutting for a different number of sharp blades and the blades having the worn place or dulling. Calculation of the power parameters of the blade CB of the geokhod with a radius of 1.6 with a pitch of the helical blade (h b = 0,6 м) was made in Microsoft Excel.…”

Abstract. The article presents the power dependencies for determining the number of blades of the cutting body of geokhod for destruction of rocks of low hardness. The obtained dependences are based on the developed method of calculation of the blade cutting body of the geokhod. The presented dependences make it possible to choose the rational number of blades of the geokhod cutting body. The intensity of the development of underground space by the countries of the world community, including Russia, is increasing. In this connection, the tasks are to increase the rate of development and to reduce the cost of work.

“…Simulation of man-made structures rock masses is convenient to carry out by the method of discrete elements, where each particle in the array structure is described separately. The study of the internal geometry (structure and texture) of man-made rock masses on mathematical models [3,4] is largely a solution for determining their physical and strength properties that may be of practical use to calculate the filtration characteristics of the dams, the stability of dumps and bulk structures.…”

Abstract. Numerical simulation of bulk technogenic rock arrays, unlike the full-scale, has a number of advantages. They are: the large amount of low cost measurements; operative selection of parameters necessary for the environment with the given properties; calculation of stress-strain state and assessment of the array sustainability; calculation of rock arrays filtration properties that are used as filters for mining enterprises sewage, etc. The article describes the method of numerical simulation of structure of bulk disjointed rock arrays, describes the basic initial and boundary conditions of the model; represents the numerical model visualization of the array, created with the use of peripheral dumping (as an array with more textured and visual segregation of granulometric composition adjustment). The basic applications of numerical modeling of technogenic rock arrays in the mining processes are described. Comparative analysis of the real and simulated array structure shows the adequacy of the numerical model and the developed for its creation algorithm, which in turn allows judging the quality of the study. Also, the adequacy of building models is supported by a high convergence of the experimental and calculated figures depending on the filtration rate values of the particle size distribution of technogenic rock arrays.
