“…Currently, there are many researches on the bearing capacity of coarse-ground, and also on the effect of the size fractions [5][6][7][8][9]. Researches of such ground are carried out on increased shear devices or in the field [10][11][12][13]. Consider some famous results [1][2][3] on the effect of large fractions of strength base.…”

The content of large soil fractions in soils complicates the experimental part of the research, but, the modeling method makes it possible to determine the effect of soil filler on slope stability. The article presents the results of experimental study of the strength of coarse-clastic soils with different percentages of large fractions of gravelly soil (up to 20 mm) and aggregate (up to 5 mm) in the study of slope stability. The studies were carried out on three types of experimental equipment, which confirms the reliability of the results obtained. Recommendations are given for applying the values of the strength characteristics of coarse-grained soils in calculating the stability of slopes. The results of the tests are carried out in a tray and shear testing devices. Mixture of soil fractions from 2 mm to 50 mm. Purpose of the tests is to determine the actual parameters of soil strength j and C, taking into account the effect of impurities on the stability of slopes. Reliability of the results confirmed the comparability of the results of previous tests. Tray allows for testing models of slopes composed of mixtures of sand fractions from 2 mm to 20 mm. Model sizes slopes are defined relative to the size tray. Tray dimensions ‑ length 1400 mm, width 500 mm, height 1000 mm. The design of the shear device allows to investigate coarse soils of different factions. The diameter of the fractions were tested for shear device area of 100 sm2 is from 2 mm to 20 mm. The diameter of the fractions were tested for shear device area of 1000 sm2 ‑ from 5 mm to 50 mm. The experiments were performed in the laboratory "Geotechnics in Construction" in KazGASA.

Purpose. To develop a mathematical model for a system of amber extraction based upon physical cumulation and deflation effects under the conditions of turbulent flows. Methodology. Theoretical simulation of the extraction processes took into consideration use of a basic aggregate, converting processes, compounding processes, modification processes, aggregating processes, processes of rotation series development involving practices of design and operation of the available similar facilities, design solutions, and widespread unification of both components and assembly units. Analysis of the gained theoretical and practical experiences helped simulate processes of amber extraction from sandy and clay rocks with stope filling. Findings. Rock mass loosening by means of hydromonitor jets, operating tangentially in a casing while developing swirling pulp flows, has been simulated mathematically. A procedure to prepare filling material from mine tailing by means of a preparator, located within a settling pond, has been substantiated. The research, concerning mineral disintegration, has helped identify that the average value of the maximum deflector radius, shaped as a result of counter jetting action, is Rmax = 0.30.5 m; at the same time, the average value of the maximum radius of a hole, shaped resulting from helical jetting action around suction pipe, is Rmax = 0.3m. Originality. For the first time, a mathematical model to use cumulation and deflation effects for a mineral disintegration has been developed as well as for preparation of filling material from mine tailing. The model reflects twists of helical 6585 jetting action with the maximum 0.5 m deflector radius and development of turbulence improving stope filling efficiency. Practical value. The proposed procedure is the theoretical background to develop automated system of amber extraction from sandy and clay rocks, which will improve productive capacity of the mining process substantially.
