Published: February 2022

Abstract
At the fields of Rosneft Oil and Gas Company, effective technologies are used to increase oil production and oil recovery ratio. To this end, systematic work is carried out to extract hard-to-recover oil reserves. Side boreholes (BS) cutting, which helps to increase oil recovery and actually replaces well compaction. Piezometric and unprofitable wells, as well as wells with leaking production strings, are identified when selecting candidate wells for planning BS and horizontal wells (HW). Maps of residual oil-saturated thicknesses are also considered, according to which localization zones of oil reserves not involved in the development are determined, in order to select areas for drilling. For rational selection of measures, forecasting of drilling results should be carried out using a hydrodynamic model and full seismic studies. First of all, the proximity of the water injection front from the existing injection pool of wells is determined in order to avoid the risks of sharp watering.

Abstract
To reduce environmental damage from mining, it is important to minimize the number of endogenous fires caused by spontaneous combustion of hydrocarbons. However, the existing technical solutions have significant limitations and require large investments. The purpose of the study is to develop technology and software for 3D thermal 3D mapping of coal warehouses and coal mining enterprises, which makes it possible to quickly detect potential foci of fire, carry out their prevention, and also minimize the time to extinguish the fires that have arisen. In the work, unmanned aerial vehicles were used as carriers of a photo camera and a thermal imaging camera, as well as software developed with the participation of the authors for processing thermal imaging images and video materials. The survey data were subjected to computer processing and loaded into the geographic information system. The resulting 3D thermal model was used to identify hot spots where fires are possible, as well as for forecasting. Testing of the hardware and software complex in a coal mine showed that the thermal 3D model correctly displays the temperature of coal seams at a considerable depth (over 3 meters). This allows you to quickly identify foci of fire and eliminate them. Research prospects are associated with replicating the results and building 3D thermal models for a larger number of coal enterprises.

Complex processing of phosphogypsum
Authors: Daminev R R , Kh Kurbangaleeva M 
Published: February 2022

Abstract
The raw material base for many branches of the chemical industry is depleting; the issue of involving in the production of both raw materials with a low content of useful components and industrial waste becomes more and more urgent. Waste from production falls as a dead load on the cost of production of enterprises and often gives rise to a number of difficult-to-solve problems. This also applies to phosphogypsum ,i. e. a large-tonnage waste from the production of phosphoric acid by the sulfuric acid method. Phosphogypsum contains elements such as Ca, Mg, F, P, Si, Sr and rare earth elements. Secondary waste generated in this case is of limited demand and is practically not used. The complex composition of phosphogypsum as a raw material for the chemical industry should be considered as an opportunity to reduce mining, provided that the valuable components that make up its composition are maximally extracted from it into marketable products. The problem can be successfully solved using the technology of complex processing. Complex processing can be conditionally divided into three stages: obtaining ammonium sulfate or sodium sulfate; concentrate of rare earth elements; calcium silicate or calcium carbonate. Phosphogypsum processing is aimed at solving environmental problems that exist during its storage in dumps at phosphate fertilizer enterprises; at the same time, the negative impact of phosphogypsum components on the environment is reduced.
Optimization of the main parameters of a mixing box in a periodic mode of operation in the preparation of liquid lumps in animal husbandry
Authors: Solonshickov P N 
Published: February 2022

Abstract
The article discusses the problem of developing means that can increase the efficiency of mechanization of the process of preparing liquid feed in animal husbandry. Design bureaus, research and technological institutes for mechanization and electrification of agriculture have developed new progressive technologies, as well as kits, units, machines and apparatus for animal husbandry and fodder production. On the basis of this technique, complex mechanization of farms is being introduced and livestock complexes with industrial production technology are being created. But recently, the widespread use of domestic machines for the preparation of liquid feed mixtures has not been presented. Therefore, an experimental setup is proposed that combines three functions: a batcher, a pump and a mixer, which ultimately allows to obtain a mixture of good quality. The article provides a program and research methodology for the installation. For this, a special stand has been developed, which makes it possible to determine the parameters of the mixture quality. As a search for the optimal combination of factors for the optimization criteria: the degree of homogeneity and, plan 33 was chosen. Experimental studies have shown the range of the installation feed at different speeds of rotation of the impeller shaft. Mixing studies have confirmed the effectiveness of the design of the plant and its components: dispenser, pump and mixer. With the help of experimental planning methods, the main factors influencing the mixing process are identified, and the optimal parameters of the mixture quality are determined.

Published: February 2022

Abstract
The article presents the results of theoretical and experimental studies of the operating modes of screw dispensers. The experimental part of the research was carried out on a laboratory installation. A frequency-controlled method of controlling the electric motor of the installation was used. When deriving theoretical dependencies and processing experimental data, the laws of mechanics and mathematical processing methods were applied. The research was reduced to the search for dependencies of the productivity of the screw dispenser on the rotation frequency of the screw dispenser. Four possible schemes of operation of screw dispensers were considered. As a result of the analysis of the obtained data, linear dependencies describing the change in the speed of rotation of the screw from the acceleration (braking) time are derived. Using the obtained experimental expressions and knowing the structural dimensions of the screw dispenser and the physical and mechanical properties of the metered materials, it is possible to determine the theoretical performance of the screw dispenser. The developed method is applicable to the calculation of all dispensers and can be used in the development of machines for agriculture and other industries.

Published: February 2022

Abstract
Combined feeds are a determining factor in the price formation for meat and dairy products. Currently, the time of combined feed storage under normal conditions is about two months. This circumstance requires the interconnected work of the feed mill and the livestock enterprise. When small farms are provided with fodder, the smooth work of the feed mills is disrupted, and the costs of the combined feed production increase. Therefore, the improvement of storage methods for small batches of feed will help reduce the cost of production due to the smooth operation of feed mills, and meet the demand of small businesses.

Authors: Kurochkin A A , Frolov D I 
Published: February 2022

Abstract
The article deals with the problem of increasing the efficiency of preparing heifers for lactation. A modernized device for combined massage of the udder of heifers is proposed. The device allows you to regulate the intensity of the pneumatic effect on the mammary gland tissue of the animal. The analysis of the working process of massage devices operating according to a two-chamber scheme is performed. A diagram of the pressure change in the massage bell and the massage element of the device was obtained. The design of the device allows you to get two technological modes of operation of the device for preparing heifers for lactation. The positive side of the presented design of the massage device can be attributed to the ability to control the intensity of the pneumatic and mechanical components of the massage. Also it allows to eliminate the disadvantages inherent in the prototype due to a more rational diagram of pressure changes in the massage bell and its executive mechanism - the massage element. The massage device provides adjustable parameters of the pneumatic component of the massage for the bell and the element, respectively, in the range from 10–17 kPa and 19–28 kPa. The data obtained agree well with the requirements for the technological process of preparing heifers for lactation.
Experimental studies of a granulator with a cooling system using a standard matrix for the development of waste-free industries
Authors: Zykin A A 
Published: February 2022

Abstract
The use of renewable resources and the development of waste-free industries are becoming more and more urgent as the environmental crisis is growing and energy resources are decreasing. Wood processing is one of these areas. Dumps of forest waste can cause fires. The use of wood processing waste as a fuel is impractical due to their low calorific heat value. Therefore, such waste is first subjected to special treatment to obtain fuel briquettes or pellets using special lines, the basis of which is a granulator. However, the granulation process takes place within a strictly defined temperature range. Therefore, one of the main problems to be solved is the stabilization of the heating of the granulator matrix. To solve this problem, we have developed a scheme of a cooled matrix granulator. We carried out a series of experiments in order to determine the efficiency of the proposed granulator. The aim of the first stage of our research was to study the working process of a granulator with a cooling system using a standard matrix. We have come to the conclusion that granules of the required quality in a granulator with a standard matrix are not obtained in all operating modes.

Published: February 2022

Abstract
The article presents the results of scientific research conducted to assess the effectiveness of applying the methods of local pre-sowing fertilization. The research was carried out in a field stationary experiment in a seed crop rotation system. The research object of the study was wheat of the “Novosibirskaya 31” variety. In 2020 and 2021, in the Sukhobuzimsky district of the Krasnoyarsk region, the experiments were laid on the local application of mineral fertilizers by a machine-tractor unit using new replaceable working bodies developed in previous studies [1,2]. Deep-local applying the mineral fertilizers with the use of new replaceable working bodies for the cultivator for continuous tillage, the yield of grain crops and the productivity of the soil-fertilizing unit increase. There is a statistically significant (p<0.01) positive correlation between the yield in different variants of the experiment in 2020 and 2021 (Pearson’s correlation coefficient is 0.852, Spearman’s rank correlation coefficient is 0.905), which indicates a high stability of the distribution of experiments by yield, regardless of weather conditions of the year. When fertilizers are applied before sowing locally to a depth of 8-10 cm, the grain yield increases by 3.2-12.1% compared to the control in 2020 and by 26.2-40.7% in 2021. A comparative analysis of wheat yield in experimental variants relative to the background (N40) showed that when applied locally in spring, simultaneously with cultivation, the yield increased by 10.6% in 2020 and 20.9% in 2021 against 2.5 and 7.5%, respectively, scattered under cultivation. The mathematical analysis of the obtained experimental data showed that the depth of application is statistically significant (p<0.001) affects the yield and the optimum depth of planting is 8-10 cm.

Published: February 2022

Abstract
Layer-by-layer loosening of soil contributes to an increase in energy consumption for its cultivation. Thus, in order to reduce traction resistance, a blade with a variable crumbling angle has been developed. In the blade stand area, it is proposed to increase crumbling angle of the chisel plow by analogy with working bodies of the chisel plow to 300, and the blade wing should be made in the form of a flat-cutting blade with a small crumbling angle. To substantiate paw profile in the strut zone, a static equation of action of forces has been drawn up depending on curve shape of the front. Distribution regularity of specific soil pressures on the blade has been determined. To verify results reliability of theoretical studies, a field experiment was carried out. Behind the tractor wheel, a beam with 4 proposed blades was installed, first row blades were set to a depth of 7 cm, and second row blades, following the trail of the first blades, to a depth of 15 cm. Using method of soil sifting on sieves with round holes, structural and aggregate composition of soil was determined along the track. Maximum lump size in the traditionally treated area is 105 mm, while maximum lump size in the layer-treated area is 80 mm, which is 24% less. Use of layer-by-layer processing in the areas compacted by the tractor propellers made it possible to improve soil pulverization quality, and thereby reduce negative factors of overcompaction by tractor running system.

Abstract
Using the method of calculus of variations, the task was set to determine the shape of the paw profile of a plane-cutting cultivator with minimal traction resistance. Based on this functional, the Ritz differential equation was compiled, which makes it possible to find the value of the functional by possible linear combinations of selected functions with constant coefficients composed of the first terms of the sequence, as a result of which an expression describing the required profile of the working organ was obtained. The Ritz differential equation made it possible to determine a family of extremals for a given functional: the desired curve belongs to this family and satisfies the boundary conditions of the problem. Using the finite element method, the three-dimensional problem of substantiating the profile of the tillage working body was solved. As the results of experimental studies have shown, a working organ with a reasonable profile has a lower energy consumption by 15-35% compared to traditional ones, while reducing the ridge of the soil surface along the width of the treatment.

Abstract
The improvement of pre-plant treatment is possible on the basis of hot and cold mist of biopreparations. The device to treat seed tubers consists of a box made of thin metal or plywood on a loader conveyor with a rubber shutter to ensure the tightness of the treating area. Mist treatment occurs when the oncoming movement of tubers, ensuring fine droplets. Hot mist of biopreparations promotes heating of the surfaces of tubers by 1-2° C, accelerating physiological processes in them. The analysis of plant development has established that the best result is achieved by treating potato seed tubers of “Lily” variety with hot mist of biopreparations, and the highest efficiency is obtained from biopreparation Potassium humate. The value of the vegetative activity index in plants treated with hot mist of Potassium humate is 18 % higher in comparison with plants in the control plot not treated with biopreparations. The height of the stems of potato plants is 7.3 % higher in those treated with hot mist of Potassium humate than those treated with cold mist of the same preparation. In comparison with plants in the control plot, it is 75.1 % more. The number of leaves on potato bushes when treated with hot mist of Potassium humate is 13.1 % higher in comparison with those treated with cold mist of the same preparation and by 18.9 % in comparison with the values in the control plot. Studies have shown that the treatment with the mist of biopreparations helps to accelerate the development of plants, and treating with hot mist increases the physiological activity of tubers.

Abstract
Pre-plant treatment of barley seeds with hot mist of biopreparations has some protective effect against harmful microflora, improves the absorption of nutrients from the soil, and increases the physiological activity. For pre-plant treatment of barley seeds of “Creshendo” variety, hot mist of the following biopreparations was used: Baktofit, Potassium humate, Fitosporin M, Innopraktika complex. The evaluation of the influence of the treatment was carried out according to the elements of the structure of the yield of plant samples and the physical-chemical indicators of grain samples from experimental plots. The statistical assessment showed good reliability (coefficient of variation was about 10). The number of productive stems per 1 m2 was increased by the hot mist treatment with Innopraktika complex by 54.1 % and Fitosporin M by 31.0 % in comparison with the samples from the control plot. The weight of 1,000 grains exceeded by 5.9 % in samples treated with Potassium humate and by 4.6 % with Fitosporin M. The highest biological yield was achieved when hot mist treatment with Innopraktika complex (50.822 dt/ha) and Fitosporin M (43.17 dt/ha). In terms of physical-chemical indicators, the best values were obtained when treated with Fitosporin M and Potassium humate in comparison with control samples: an increase in the mass fraction of starch in grain was by 10.8 % and 5.1 %, respectively; crude protein increased by 5.4 % and 6.9 %; an increase in the exchange energy in both cases was by 0.8 %. The best effect of pre-plant treatment of barley seeds of “Creshendo” variety is achieved with the use of hot mist of biopreparations Fitosporin M and Innopraktika complex.
