The use of self-propelled mining equipment with diesel drive on alluvial mines makes it possible to significantly increase labor productivity and thereby reduce the cost of mining the mineral, but at the same time the pollution of the mine air with exhaust gases increases sharply, and this requires the intensive ventilation of the mine. The exploitation of self-propelled mining equipment on placer mines in the summer will be accompanied by intensive thawing of frozen loose rocks because of the relatively large volumes of warm air supplied to the mine. The safety rules prohibit the development of permafrost deposits by lavas at a temperature of sand and roof rocks (at a depth of 0.5 m from the exposure plane) from -1оС and higher. For highly mechanized all-the-year-round alluvial mines, at the design stage it is necessary to make predictive calculations of the temperature regime, including in the stopes, taking into account the thermophysical parameters of the air jet, heat sources and technological parameters of mining, which will allow selecting parameters of the development system under which a safe and the effective conduct of clearing works. As shown by the results of mathematical modeling for the alluvial diamond deposit "Solur" conditions, it is possible to use high-performance self-propelled mining equipment in the summer period with the appropriate parameters of the ventilation jet and the organization of the technology of cleaning operations.

The problems of predicting heat and humidity conditions in various mine structures, as well as taking into account induced pollution of frozen soil and pollutant migration in permafrost strata need new mathematical models. It is required that these models take into account to a fuller extent features of physical freezing and thawing processes in pore water. It is also of the current concern to develop new software tools and methods for the numerical solution of model problems on heat-moisture-salt transfer in multi-dimensional domains with regard to phase ice-solution transition. This article proposes a method to solve the problems of heat and and mass transfer with phase transformation (freezing-thawing). The method involves splitting of the initial problem of heat and mass transfer with phase transformation with respect to physical processes. Such processes are assumed to be diffusion transfer of heat, moisture and soluble salt between points of meshing, as well as the processes of redistribution in the point neighborhoods which are assumed to be isolated systems...

For the extraction of mineral reserves of Udachnaya Pipe under the open pit bottom, the system of one-stage caving under a safety cushion is accepted. To ensure the mine safety, the cushion should preserve looseness within the whole mine life period. Developed for the analysis of ice accumulation, the general mathematical model of heat and mass transfer takes into account three interfering processes running in the safety rock cushion, namely, seepage of moisture from atmospheric precipitation, leak of moist air and heat transfer during phase transformations of moisture. It is analyzed how atmospheric precipitations and mine air affect the process of ice accumulation in the safety cushion. The mathematical model allows calculating ice formation in voids of the cushion owing water seepage and condensation of moist mine air. The model efficiency is discussed in terms of the calculations for a rock safety cushion 30 m thick. The calculations are performed for readily and weakly permeable rocks. For the readily permeable rocks, the maximum ice content is 0.1 at a depth of 1.5 m in the first summer and 0.15 at a depth of 2.2 m in the first winter. In the second summer, the maximum ice content is also observed at the depth of 2.2 m; moreover the ice content grows, which blocks pores. In case of the weakly permeable rocks, ice accumulates at a depth of 1.9 m. At the bottom of the cushion, rocks gradually thaw under leakage of air from the mine irrespectively of the season. In addition, ice accumulates in the cushion owing to condensation of moisture from the mine air. The ice content curve contains a characteristic “hump” which drifts toward the upper boundary of the cushion with time. The hump drifting is less intensive in the weakly permeable rocks. The developed mathematical models of heat and mass transfer and the programs for calculating temperature and moisture content of the safety cushion under moisture seepage can be used to predict rate of adfreesing in rocks and to control safe and uniform subsidence of the cushion. The calculation results will help develop guidelines on making safety cushions, maintaining their year-round flowability and permeability, as well as improving safety of underground extraction of diamond pipe reserves

The mechanisms of change in external and total specific surfaces under alternating thermal forces are determined for limestone and kimberlite from a few diamond deposits in Yakutia. The test specimens of rocks differed in grain sizes by an order of magnitude: -20+10 mm and -2+1 mm. The external specific surface of the specimens with the grain size of -20+10 mm was determined by the grain size analysis. After 10 cycles of freezing-thawing in aqueous medium, the external surface of carbonate-bearing rocks from Udachnaya and Aikhal Pipes increased by 3-12 times. The external surface of kimberlite from Internatsionalnaya and Mir Pipes enlarged by 8-14 times. The total specific surface of the specimens with the grain size of -2+1 mm was estimated using the BET method on Sorbtometr-M analyzer. The tests show that after 5-10 cycles of freezing-thawing in aqueous medium, the increase in the total specific surface makes 38% for kimberlite from Udachnaya Pipe, 2-12% for carbonate-bearing rocks from Udachnaya Pipe (dolomite, dolomitic limestone, limestone) and 5% for limestone from the Mokhsogollokh surface mine. The intensity of formation both of external and total specific surfaces depends on the saturation and freezing medium, porosity and mineral composition of rocks and on the scale factor. The research findings help understand the mechanism of initiation and growth of structural defects in rocks under alternating thermal forces, which finally result in total disintegration

The work is dedicated to cryolitezone pit wall stability problem solution by heat mass exchange processes controlling on quarry face surface with hydro and thermal isolation application. Two-dimensional mathematic model of heat exchanging processes in filtration quarry face rock mass is worked out, considering moisture phase change and heat transfer by water filtration. Mathematical model allows to forecast temperature field forming process in quarry face rock mass depending on parameters: climatic conditions (ambient air temperature change dynamics, snow thickness, wind speed, rain intensity), rock thermophysical and filtrational properties, quarry face constructional features (quarry face geometry, slope angle), thermophysical properties and geometrical dimensions of quarry face surface thermal isolation. Developed mathematical model solved by numerical method, namely finite-difference method, and realized in the form of Microsoft Windows OS-based application. The research results of bench edge hydro-thermal insulation parameters influence to reduction of wrecking temperature and humidity influence of environment to opencast bench are presented. Studies showed, that by controlling of edge hydro-thermal insulation parameters it is possible to keep frozen state of rock mass under bench edge during a year.

Mathematical model of ventilation air and rocks heat mass exchange processes in cryolitezone extensive mine workings, with moisture vaporization and condensation taken into account is proposed. Working’s equivalent radius sets, equation derived in cylindrical coordinates. Internal radius of the area corresponds to working’s radius, while outer radius is taken from spreading condition of heat influence zone around the working for taken temporal period. Energy conservation equation in working derived with air velocity and ribside heat exchange taken into consideration. In case working’s air temperature drops below dew point, moisture condensation occurs. Working’s surface vaporizing processes calculated with Lewis correlation taken into account. Moisture phase change in rocks around the working taken into consideration. Mathematical model is numerically solved by finite difference method. It is shown, that mass exchange processes in summer neglecting leads to significant miscalculation. Developed model numerical implementation allows to calculate ventilation air temperature and it’s relative humidity variations dynamics subject to working’s hydrothermal conditions, that is important to mines thermal conditions prognosis and mining safety providing.

The article presents some research findings on the effect of basalt fiber 6 mm in length with a diameter of 23 μm on strength of fine-grained concrete (cement-and-sand matrix) under bending, compression and alternating thermal forces. It is found that the maximum increase in the bending strength of concrete by 31-36% is reached at the fiber content of 4-6% of dry mixture weight (cement+sand). There is no considerable increment in the compressive strength; moreover, at the fiber content of 6%, the compressive strength decreases by 16% as compared with the initial (non-reinforced) specimens. Exposure to 5 accelerated freezing-thawing cycles (freezing temperature 50±5°С, State Standard GOST 10060.2-95) resulted in the reduction in the bending strength of non-reinforced specimens by 73% as against the untreated specimens whereas the strength of the specimens with the fiber content of 2 and 4% lowered by 40 and 35%, respectively. In the compression testing, 5 freezing-thawing cycles decreased the strength of the check non-reinforced specimens by 47% while the decrease in the strength of the reinforced specimens with the fiber content of 2% made 5% as against the check specimens, which corresponded to the freeze resistance grade F200 in compliance with GOST 10060.2-95. The obtained results prove that disperse reinforcement of fine-grained concrete with basalt fiber can increase freezing resistance of concrete and its resilience under bending and compression, which expands application field of concrete.
