Outstanding scientists who worked at the department
Among the teachers of the department were prominent scientists: O.M. Dinnik, S.A. Zaborovsky, SB Scharbe (Professor, Master of Astronomy, in 1907-1913 he headed the Department of Analytical Mechanics), A.Sh. Lokshin, teachers VE Zagulin, NM Dobrynin, A.S. Ilovaisky, GA Skuratov; head of the section of theoretical mechanics Ya.I. Grdina; heads of the section of mining mechanics VM Makovsky, KE Roerich; associate professors A.O. Spivakovsky, AA Gorin, NP Grishkova, VS Makarov.
One of the main directions of scientific research of the staff of the department since its creation is the dynamic theory of calculation of mine hoists. Professor SA Zaborovsky studied the calculation of steel ropes, mine stands and fasteners. The formulation and solution of these issues at that time were innovative.
Created by Acad. OHM. Today, the mechanical testing laboratory has become a testing center for steel ropes and other mining equipment in Ukraine. OHM. Dinnik created scientific schools in the field of theory and calculation of hoisting ropes, stability of elastic equilibrium, the doctrine of rock pressure. To study the longitudinal oscillations of ropes with a load located at the end, he first considered the rope as a continuous elastic system. The coefficients of stability, which he found, were included in the reference literature. Considering in the first approximation the rock as an elastic isotropic medium and using the means of the theory of elasticity, O.M. Diary determined the law of distribution and the magnitude of stress in the mine workings. His study of the curvature of boreholes and dynamic calculation of the impact rod is widely known.
The student OM Dinnik, prof. A.Sh. Lokshin received his doctorate in applied mathematics after defending his dissertation on the topic: "Dynamic stresses in hoisting ropes." In the monograph devoted to the determination of dynamic stresses in hoisting ropes of constant length and variable cross section, the problems of sudden stopping of the upper end of the rope, transmission of speed to the final load, sudden addition of final load and rope weight, accelerated speed of upper end, and ropes of variable length. This work was an important stage in the development of the doctrine of the dynamic processes that take place in hoisting ropes. It became the basis of a number of studies in this direction. Many works by A.Sh. Noodles are translated into German, French and English.
Professor F.V. Florinsky was a student of A.Sh. Lokshina and a follower of the scientific school OM Diary for the calculation of mine ropes, the choice of their optimal parameters and forecasting their durability. He was the first to solve the problem of deceleration limit values during safety braking of a mine hoisting machine. The results of many years of research by prof. F.V. Florinsky reflected in the monograph "Dynamics of the mine hoisting rope." In this monograph for the first time the acceptance of the transverse dimensions of the lifting rope is substantiated. This monograph is a table book of several generations of scientists, including students F.V. Florinsky, who worked in the field of steel rope theory. In different years, many scientists and teachers have devoted their research to the dynamic theory of calculation of steel ropes, including Acad. Academy of Sciences of Ukraine, prof. V.A. Lazaryan, prof. NP Grishkova-Dinnik, associate professors IA Lokshin, E.M. Karasyk, E.G. Stepanov, DN Kosenko, SI Lyakhovytsky and others.
The student of prof. F.V. Florinsky, Leonid Viktorovich Kolosov (1938-2000), a scientist in the field of mine lifting. In 1960 he graduated from the Dnipropetrovsk Mining Institute with a degree in Mining Machinery. For three years he worked as a design engineer at the Kamyshburun Iron Ore Plant, after which he completed his postgraduate studies and in 1967 defended his dissertation. L.V. Kolosov is a successor to the scientific school of theory and calculation of mine hoisting ropes, which was formed at the Mining Institute AN Dinnik and F.V. Florinsky. L.V. Kolosov studied the dynamics of steel ropes in terms of their interaction with the lifting machine. His study of the joint solution of the mechanical system and the control system of the drive and brake of the hoisting machine was reflected in the monograph "Vertical transport at mining enterprises" (1975). Under the leadership of LV Kolosov created a new scientific direction for the calculation and design of flat rubber ropes, developed a theory of calculation of these ropes, their design, technical documentation for the manufacture and operation. Created by L.V. Kolos ropes of the second generation since 1995 and to the present are manufactured at the RMZ of JSC "Kryvbaszalizorudkom" and are operated on all multi-rope lifts of Kryvbas, on coal mines of Russia, Ukraine, Kazakhstan. Research on the theory of fatigue failure of ropes is summarized by him in his doctoral dissertation "Scientific basis for the development and application of rubber ropes hoisting installations of deep mines" (1987). In 1988 he was awarded the academic title of professor. He is the author of more than 200 scientific papers, under his guidance 9 graduate students defended their dissertations, five - became doctors of technical sciences. A follower of the scientific school of Professor LV Kolosova, Professor Ropay VA, published more than 140 scientific papers in this scientific direction, received 30 patents for the design of steel and rubber ropes, conveyor belts and methods of their manufacture. With the participation of prof. Ropaya VA 10 technical conditions for new rope constructions were developed and introduced into production. According to the patent of Ukraine № 21061, published on 15.06.2001, bulletin №5, “Flat balancing rope” (authors: Kolosov LV, Ropay VA (NMU), Shido MM, Savitsky VI ( OJSC Kryvbaszalizorudkom)) on the basis of a license agreement for the first time in the CIS produced flat rubber balancing ropes (SCC) in Kryvyi Rih, OJSC Kryvbaszalizorudkom. SCCs are operated in Ukraine, Belarus, Kazakhstan, Russia.
Since 1981, a new area of research has appeared at the department - the study of the dynamics and strength of the rolling stock of railway transport and bridge structures (Prof. SE Blokhin). Mathematical modeling, large-scale natural tests have made it possible to obtain a number of technical solutions that reduce the wear of wheelsets and rails, increase the durability of bridge structures, increase the safety of quarry trains. In 1988, a branch research laboratory of the dynamics and strength of load-bearing structures of artificial structures of mining and metallurgical enterprises in southern Ukraine was established.
The dynamics of lifting installations was studied by MA Черниш, А.М. Obukhov, VV Bezpalko, L.Ya. Fomicheva, TI Жигула, К.С. Zabolotny, VP Франчук, А.С. Poversky, MV Half-width. The results of research by these scientists made it possible to substantiate new means of designing high-performance mine hoists, to ensure the safety of their operation at great depths. Another area of research of the department is the study of the dynamics and strength of mining and beneficiation machines and structures. Professors RP took an active part in this direction.

Associate professors VP worked on the creation of structural elements of enrichment equipment. Ravishin and VV Sailor. The results of their research made it possible to increase the efficiency of operation of vibrating screens and butar with rubber-string strings. Prof. R.P. Didyk formed a new scientific direction at the department - the use of explosive energy for welding of dissimilar metals and strengthening the parts of mining and metallurgical machines. A group of scientists (Prof. IV Belmas, Prof. LV Kolosov) substantiated and introduced into the practice of designing the parameters of belt conveyors in transition areas, which increase the shelf life of rubber bands up to 5 years, developed a theory for calculating belt conveyors.
Since 1970, a group of researchers led by prof. B.V. Vinogradova worked on the creation and improvement of large ore mills and developed a method of dynamic calculation of large gearboxes used in mill drives, as well as a method of calculating the durability of open gears. Since 1981, a new area of research has appeared at the department - the study of the dynamics and strength of the rolling stock of railway transport and bridge structures (Prof. SE Blokhin).
