Abstract. The paper describes the justification of georadar equipment used for research of internal structure and monitoring of mining structures at mining enterprises of Kola region. Measurements were performed by longitudinal and transverse profiling using Ramac/GPR X3M georadar complex equipped with screened antennas. The interpretation of the results was based on the detected patterns of distortion of the induced electromagnetic field due to the difference between the physical properties of the rocks of the main massif and the internal zones of inhomogeneity’s (fault tectonics, areas of increased fracturing and water saturation). Intensity of wave field distortion is shown to be determined by contrast of physical properties of rocks and depth of zone location. Numerous studies have confirmed the feasibility of using this georadar equipment to solve a number of mining problems.

Keywords: georadar equipment, mining structures, internal structure, heterogeneity, water saturation.

Abstract. The paper proposes a case for the development of the future specialist for the protection of the complexity of systemic creative thinking, perseverance in achieving the goal of professional and research activities by solving a number of interrelated problems in the analysis of working postures, establishing ergonomic risks and identity trauma, determining the cost of purchasing a variety of equipment that can help reduce injuries or diseases of the musculoskeletal system and increase productivity and substantiate the feasibility of yoga. with a loss of purchasing comparing the treatment and rehabilitation of workers. This approach shapes the student's imaginative thinking, ability to make informed decisions. To develop an effective information system of process support at all stages of management of the educational process and to provide operational control of the parameters of the educational process, in which the level of mastery of competencies acts and to adequately respond to their deviation from the planned values.

Keywords: ergonomic risk, industrial hazards, safe work, car repair, "REBA" method.

Abstract. The article is devoted to the methodology of the use of mathematical modeling in the process of teaching Higher mathematics to students of technical specialties. In particular, the electrical system was investigated, which consists of a resistor, a coil and a capacitor. It was analyzed of the current in the circuit, the elements of which are connected to the source of the EMF – to the battery or generator. The model is based on the theory of differential equations using computer technology and tools graphical interpretation of the solution.

Key words: electric circuit, resistance, inductance, capacitance, voltage, charge, current, differential equation.

Abstract. Modern technologies are based on interdisciplinary studies that determine the need for integrative training of engineers for innovation. The requirements for innovative engineers are formulated and a comprehensive approach to the formation of engineering competencies is substantiated. To meet the real needs of employers in competent specialists will allow the implementation of a multi-level competence approach based on the principle of "from highly specialized qualifications to world-class competencies" with the focus on solving topical science-intensive tasks in industry. The vector of further development of Donbass State Engineering Academy as the center of technological development of the north of Donbass. We consider interdisciplinarity, the commercialization of knowledge, the creation of technology transfer systems, and the incubator of startups and techno-starters as growth points.

Keywords: knowledge economy, innovative engineering activity, engineering education, innovative engineer, integrative training, interdisciplinary knowledge.
