Актуальность статьи объясняется необходимость поиска новых ресурсов повышение эффективности использования недр, в том числе, за счет рационального использования геомеханических особенностей скальных массивов при техногенном воздействии на них и механизма взаимодействия пород, слагающих массивы скальных месторождений. Объектом исследования служат структурно напряженные скальные массивы Садонского рудного узла. Целью исследований является оценка перспектив технологий разработки месторождений при освоении запасов в условиях техногенной ослабленности массивов. Методы решения основной задачи исследования образуют собой комплекс, в том числе, систематизация связанных с управлением массивом сведений, разработка критериев эффективности добычи руд и формирование концепции ресурсосберегающей технологии разработки месторождений. Результаты и обсуждение результатов. Сформулирована концепция технологии разработки месторождений на основе методов управления состоянием массива путем назначения оптимального уровня напряжений, формируемых совокупностью сейсмотектонических воздействий и техногенной сейсмичности. Дана типизация методов расчета устойчивых пролетов выработок. Приведены примеры решения горнотехнических задач рекомендуемыми методами расчета. Предложена схема-алгоритм взаимодействия параметров управления массивом. Определено, что перспективы технологий разработки месторождений Садонской группы связаны с реализацией концепции управления массивами пород путем регулирования величины напряжений. Доказано, что учет геомеханических факторов позволяет на всех стадиях отработки месторождения корректировать параметры разработки с повышением качества добываемых руд и уменьшением опасности для работающих. В этих условиях удовлетворительные показатели могут быть обеспечены только на первой стадии разработки при выемке первичных камер. Отработка целиков во вторую стадию увеличивает напряжения до критического состояния, что сопровождается потерей запасов или снижением качества руд до убыточных пределов кондиций. Рекомендовано отработку новых запасов и доработку имеющихся запасов осуществлять по комбинированной схеме: ценные руды с закладкой технологических пустот твердеющими смесями, руды с меньшим содержанием металлов выщелачиванием с использованием хвостов подземного выщелачивания для управления напряжениями, а выщелоченные руды выполняют искусственных целиков, перераспределяя техногенные и природные напряжения. The relevance of the article is explained by the need to search for new resources to increase the efficiency of subsoil use, including due to the rational use of geomechanical features of rock massifs with anthropogenic impact on them and the mechanism of interaction of rocks composing rock massifs. The object of study is the structurally stressed rock massifs of the Sadon ore cluster. The aim of the research is to assess the prospects of field development technologies during the development of reserves in conditions of technogenic weakening of arrays. Methods for solving the main research problem form a complex, including the systematization of information related to managing the array, the development of criteria for the efficiency of ore mining and the formation of the concept of resource-saving technology for developing deposits. Results and discussion of results. The concept of field development technology is formulated on the basis of methods for controlling the state of an array by assigning the optimal level of stresses generated by a combination of seismotectonic impacts and technogenic seismicity. Typification of methods for calculating stable spans of workings is given. Examples of solving mining problems with the recommended calculation methods are given. An algorithm-algorithm for the interaction of array control parameters is proposed. It was determined that the prospects for the development of deposits in the Sadon Group are related to the implementation of the concept of managing rock masses by regulating stresses. It is proved that taking geomechanical factors into account allows at all stages of field development to adjust development parameters with an increase in the quality of mined ores and a decrease in the hazard for workers. Under these conditions, satisfactory performance can only be achieved at the first stage of development when the primary chambers are removed. The development of pillars in the second stage increases stresses to a critical state, which is accompanied by a loss of reserves or a decrease in the quality of ores to unprofitable limits. It was recommended that the development of new reserves and the refinement of existing reserves be carried out according to a combined scheme: valuable ores with the laying of technological voids with hardening mixtures, ores with a lower metal content leaching using underground leaching tails to control stresses, and leached ores perform artificial pillars, redistributing technogenic and natural stresses.

The quality of rice determines rice prices and consumer tastes. This study aims to identify the characteristics and quality of local rice based on SNI 01-6128-2015 standards. This research was conducted by exploration method. The amount of rice taken is 1 kg. Each local rice is observed for its physical properties and quality. Physical properties include white degree, clarity, shape and size of rice while the quality of rice is adjusted to the standard quality SNI 01-6128-2015. The results show that the physical properties of local rice have white degrees which vary between 58.8 - 54.6%. Where the type of krayan rice and rice taro shows the highest white degree. The value of clarity of local rice shows in the range of 1.70 - 2.57%. The level of rice clarity affects the level of consumer preference. The size of local rice has a long and medium sized category. Long-term rice is Puy, Ikang, Angga and Red rice which are cultivated with traditional lowland rice farming systems with a length (6.5-7) mm. While medium-sized rice is the type of krayan rice and taro rice which are cultivated organically with traditional rice farming systems by the people of the highlands with a length (5.5-5.6) mm. The form of local rice has the form of lean rice (2.8-3.5) and the form of medium rice (2.2-2.8). Ikang rice, Angga and krayan have a slim shape while Puih, Keladi and Merah have medium forms.

Abstract For processing small-scale wood, as well as wood from logging and sanitary logging, small enterprises are created that use fairly large and expensive band saws of various foreign firms and domestic production, which have a high energy intensity of the technological process. In this regard, the development of a resource-saving band saw machine that improves the quality of saw products and reduces the energy intensity of the technological process is an urgent task for the timber processing industry. To study the dynamics of the process of sawing wood on a horizontal band saw, it is necessary to create its dynamic model, which is a mathematical description of the interaction of the cutting process and the equivalent elastic system of the machine. The problem of the quality of wood sawing is both the accuracy of processing and the roughness of the surface to be processed. To assess the accuracy of wood sawing, two indicators were used: average and maximum undulation. As a result of the research, a new design of the band saw was developed using a dynamic model, which ensures resource saving, reducing the energy intensity of the technological process and improving the quality of the resulting saw products.

Objective. To study the efficacy of pre-sowing inoculation of soybean seeds with biological preparations in different preparative forms with and without pre-treatment of seeds under different systems of protection against weeds. Methods. Field, laboratory, biochemical, mathematic-statistical and economic. Results. In the stationary field experiment, the influence of different forms of biological preparations on the soybean growth under the conditions of the Right-bank Steppe of Ukraine has been studied. It has been established that in the seed pre-treatment, Maxim XL, which determines the increase in soybean productivity compared to the preparation Scarlet is preferred, and among the inoculants, it is preferred to choose Ryzobofit both in liquid and in the peat form. It has been proved that the post-emergent herbicides contribute to the decrease of weeds in soybean culture, which results in better conditions for the growth and development of plants, an increase in the number of nodules on the roots, and increased grain yield. The use of biological preparations contributed to an increase in not only the number of nodules on soybean plant roots, but also their mass compared to control without inoculation (7.8–76.9 or 26.7–109.7 %, respectively). Under the resource-saving system of crops protection from weeds in soybeans, higher rates were obtained in variants where treater Scarlet was used for pre-sowing treatment, and under the intense one — Maxim XL. The use of biological preparations in technology has made it possible to significantly increase yields by 0.2–0.3 t/ha (or 9.2–13.8 %) under both systems of crop protection from weeds. Conclusion. On heavy loamy chornozem on the Right-bank Steppe of Ukraine, pre-sowing inocula-tion of soybean by biological preparations is a mandatory agrotechnical measure, which, in combi-nation with seed pre-treatment, allows a significant increase in yields and contributes to improving the quality of the grain when cultivating the crop using both studied systems for protection of crops from weeds.

The purpose of research: to improve the technology of growing flax in the Western region of Ukraine on the basis of the introduction of systems for minimizing tillage, which will increase the yield of trusts and seeds. Research methods: field, laboratory, visual and comparative calculation method. Research results: Field experiments included the study of three tillage systems (traditional, canning and mulching) and determining their impact on growth and development and yields of trusts and flax seeds. The traditional tillage system included the following operations: plowing with a reversible plow to a depth of 27 cm, cultivation with simultaneous harrowing and pre-sowing tillage. The conservation system is based on deep shelfless loosening of the soil and provided for chiseling to a depth of 40 cm, disking to a depth of 15 cm, cultivation with simultaneous harrowing, pre-sowing tillage. During the implementation of the mulching system, disking to a depth of 15 cm, cultivation with simultaneous harrowing and pre-sowing tillage with a combined unit was carried out. Tillage implements and machines were used to perform tillage operations: disc harrow BDVP-3,6, reversible plow PON-5/4, chisel PCh-3, cultivator KPSP-4, pre-sowing tillage unit LK-4. The SZ-3,6 ASTPA grain seeder was used for sowing long flax of the Kamenyar variety. Simultaneously with the sowing of flax seeds, local application of mineral fertilizers (nitroammophoska 2 c/ha) was carried out. The application of conservation tillage allows to obtain the yield of flax trust at the level of 3,5 t/ha, which is 0,4 t/ha (12.9 %) more than from the area of traditional tillage and 0,7 t/ha (25 %) in comparison with mulching. In the area with canning treatment, the seed yield was the highest and amounted to 0,64 t/ha. The difference between this option and traditional and mulching tillage reaches 0,06 t/ha (10,3 %) and 0.10 t/ha (18.5 %), respectively. Conclusions. Preservation tillage, which is based on shelf-free tillage to a depth of 40 cm and disking to a depth of 15 cm has a positive effect on plant growth and development, yield and quality of flax.
