“…The assessment of mining and technical situation during implementation of new radical mining technologies [3 -11], change of physical and chemical properties under the influence of external factors [12,13] is especially important. Extraction of minerals in complicated mining and geological conditions also are presented on specialized literature [14 -16].…”

The paper represents the creation of the software simulation system, which reproduce the basic processes of mining and near production. It presents the consideration of such systems for both traditional and non-traditional mineral extraction systems. The principles of using computer recognition of processes are also presented in other processes of carbon-containing raw materials transition, as well as power production and waste utilization of mining production. These systems considerably expand the manageability of a rather complicated mining enterprise. The main purpose of such research is the simulation reproduction of all technological processors associated with the activity of mining enterprises on the display of the dispatch center. For this purpose, is used so-called UML-diagrams, which allows to simulate mining and near mining processes. Results of this investigation were included to the Roman Dychkovskyi thesis of the scientific degree of the Doctor of the Technique Sciences “Scientific Principles of Technologies Combination for Coal Mining in Weakly Metamorphoses Rockmass”.

“…Качественным доказательством существования эффекта сверхглубокого проникания (СГП) является появление новых структурных элементов в металлических преградах. Обычно в материал высокоскоростного сгустка вводят химические элементы, которые отсутствовали в исходном материале преграды [6]. Например, в качестве примера таких исследований можно рассмотреть взаимодействие железных преград со сгустками свинцовых микрочастиц.…”

Выполнены экспериментальные оценки прочностных свойств композиционного материала на базе углеродистой стали 45, созданного прошивкой матричной стали в режиме сверхглубокого проникания сгустками порошковых частиц. Импульсное динамическое воздействие сгустков порошковых частиц и последующая термическая обработка преобразуют сталь в волоконный композиционный материал. Ключевые слова. Сверхглубокое проникание, композиционные материалы, легирующие элементы, изменение физических и механических свойств. Experimental estimates of the strength properties of a composite material based on carbon steel 45, created by piercing matrix steel in the mode of superdeep penetration by streams of powder particles, have been performed. Pulsed dynamic action by streams of powder particles and subsequent heat treatment converts steel into a fiber composite material. Keywords. Super-deep penetration, composites, alloying materials, change in physical and mechanical properties. For citation. Marukovich E. I., Usherenko S. M., Javad Yazdani-Cherati, Usherenko Yu.S.

Интерес к физическим и химическим эффектам, которые проявляются в углеродистых сталях при динамическом воздействии, стимулируется потребностью современной техники в создании материалов со специальными свойствами. Непосредственным результатом действия высокого импульсного давления на стали является сжатие вещества. Полагают, что энергетически выгодно то направление физического процесса, которое ведет к сжатию взаимодействующих веществ [1]. В настоящее время известно, что повышение плотности фазы высокого давления не является общим правилом.Изменение плотности влияет на физические и химические свойства стали. Например, при динамическом сжатии в пределах более чем 13 ГПа твердые материалы испытывают превращения с образованием новых кристаллических форм; наблюдаются переходы твердых диэлектриков и полупроводников

“…The development of modern visualization methods makes it possible to significant ly expand the ways of representing and shaping all the compo nents of the lithological structure of the studied areas. The simulation system should objectively reflect the level of min ing -geometric study of the formation [9]. They also have the opportunity to adjust the overall picture of the mining in case of obtaining additional data from the exploration wells of the mine or in case of meeting by the extractive work the new ab normal formations.…”

Purpose. Creation of a favorable geomechanical situation and estimation of economical parameters at the mining area accord ing to the selection of the relevant technical and technological justification and operating modes of the mechanized fastening based on the planning of zones of variable stresses. Methodology. Methods of mathematical modeling for determination of loads for fastening of mechanized complexes, experi mental studies on stresseddeformed state of the rock mass are applied, on the basis of which rational parameters of mining and management mining pressure are formed. findings. Using the developed method of data geometrization, the lithological and geological structure of the rock mass was restored on the intersections of the surrounding wallface two of preparatory workings. On this basis, a change in the stressstrain state of a rock massif is established. This makes it possible to set the loadings on the fastening of mechanized complexes. This ap proach establishes the mathematical dependencies that determine the zones of elevated and lowered mining pressure. For the measure of transition, the socalled coefficient of lithological difference is defined. This parameter provides the possibility not only to evaluate the geomechanical situation at the extraction site, but also to establish a marginal zone for the development of reserves with traditional and radical technologies. An economic evaluation of the proposed technical and technological measures has been held separately. The results of the research will allow justifying the effective mining of coal reserves in particular geological condi tions. originality. The dependence of the lithological difference formation of rocks and stresses of the rockmass to create conditions for the development of the coal reserves has been established. An economic evaluation of the decisions was made using the well known methodology of UNIDO. Practical value. Obtained results of experimental studies with precision sufficient for practical application can be used to deter mine the parameters of underground mining and provide an opportunity to extract the coal reserves at an economically suitable level. The proposed technological solutions were checked in practical conditions for the development of the coal reserves at the site of a DTEK company mine.
