Abstract Introduction. Freight cable cars (FCC) were widely used in the USSR and other countries in the first part of the 20th century. Only in the USSR the number of FCC amounted to 190 pieces, freight volume – 116 million tons per year, ropeways length – 600 km. Research aim is to define the perspectives of using freight cable cars in the northern regions.
Methodology and results. Comparison of engineering and economic indicators of motor, railway, conveyor transport, and FCC has shown that ropeways have a number of strategic advantages over other ways of transporting solid minerals, especially in the remote northern regions and the Far East. FCC advantages: independence from the surface relief and air conditions, good opportunity to track via the shortest distance between the points of loading and unloading, etc. With the account of the achieved performance targets, FCC can be used to transport from 0.5 to 7 million tons of load per year at a distance of several tens of kilometers. With almost similar capital cost of motor transport and ropeways, FCC have an advantage by a factor of 4–5 as soon as operational costs are concerned.
Summary. Recent Russian engineering and technological solutions (application of rolling stock automated control, new materials, etc.) make it possible to consider FCC the most modern and manufacturable type of solid minerals transportation, which is easily integrated in the concept of the fourth industrial revolution.

Key words: freight cable cars; useful life; area of application; elevation change; transportation economy; automation; prospectiveness.

Abstract

Introduction. Vibratory conveying equipment is widely used in many branches of mining industry at various enterprises (concentrating mills, transfer points at railway stations, steelworks, etc.). Design of vibratory conveying equipment with new qualities requires a more detailed analysis of oscillation parameters, in particular, oscillation parameters of machine working member.
Research aim is to investigate the oscillation parameters of vibratory conveying equipment with three vibration exciters by means of vibratory equipment dynamics mathematical model.
Methodology. The nature of working member movements is studied by means of vibratory equipment dynamics mathematical model. The model is based on the numerical solution to a system of diferential equations governing the dynamics of vibratory conveying equipment with n-unbalance vibration exciters.
Results. The present article investigates the parameters of oscillations and the features of the center-of-mass motion in vibratory conveying equipment with three vibration exciters placed on one working member. As a result of numerical experiment, the impact of location of vibration exciters and eccentric torque of unpaired vibration exciters on the working member vibration parameters has been determined. The dependence between the direction of mass center trajectory and the direction of an unpaired vibration exciter rotation is studied.
Summary. The quoted results of theoretical studies through a mathematical model show that the addition of a third vibration exciter to vibratory conveying equipment design qualitatively infuences working member vibration parameters: by changing the position and eccentric torque of an unpaired vibration exciter, it is possible to get the various options of working member vibrations. Consequently, the study of new types of vibratory equipment is a very promising direction.

Abstract

Introduction. In order to protect workers engaged in shaft sinking works, artificial protective equipment (pentices) with the support element from powerful I-beams or truss structures are used. They have to withstand enormous push loading, be strong, simple in design, have less labor input during construction and dismantling.
Research aim. On the basis of the obtained results of mathematical modeling, the research aims to increase the efficiency of equipment for the deepening of vertical shafts of mines, by justifying the dynamic loads on the safety shelves and determining their rational parameters, which ensure the reduction of material intensity and labor-intensive work.
Methodology. In order to substantiate parameters and develop the design of pentices when sinking vertical shafts in case of operational winding performance, with the help of mathematical modeling, the dependencies between the skip fall time at falling height variation with the account of speed and the direction of the air flow in the shaft were determined.
Results. LLC SibGorComplexEngineering (Novokuznetsk) together with the Department of Construction of Underground Structures and Mines of T. F. Gorbachev Kuzbass State Technical University have developed several new design variants of protective pentices for vertical shafts sinking in case of operational winding performance. It is a Z-shaped structure of the offset in height, parallel to each other upper and lower protective pentices, bushed with sloped reflective metal sheets and interconnected by a vertical division wall.
Summary. Pentice design allows reducing the impact of push loading due to direction changing and kinetic energy reduction of falling bodies. Industrial testing of a new construction of wedge protective pentices proved their high reliability, efficiency and safety of operations under shaft sinking Skipovoi of Gorno-Shoria branch of OJSC Evrazruda.

Key words: vertical shaft; shafts sinking; wedge protective pentice; dynamic load; skip fall.

ABSTRACT

The research aims to study and model inter-regional interconnections in the development of mineral resource complex of the Russian Federation and determine the main vectors of their development for the implementation of RF Spatial Development Strategy for the period up to 2025. The research methodology is based on spatial econometrics tools application, such as: spatial autocorrelation of RF subjects in the main areas mineral resource complex development. Results. The spatial analysis of regions interconnection in the development of the mineral resource complex with the use of autocorrelation according to Moran method allowed us to establish RF promising centers for oil and gas production (Sakha, Sakhalin, Tomsk, Astrakhan, Samara, and Orenburg regions), gold and metal ore (Krasnoyarsk, Transbaikal and Kamchatka regions, the Republic of Buryatia and the Kemerovo region), coal (Komi Republic, Sakha and Buryatia, Novosibirsk Region, Krasnoyarsk Krai). These territories are not considered by the Strategy for Spatial Development of the Russian Federation for the period up to 2025 as priority mineral resource centers. Summary. The spatial development strategy of the Russian Federation for the period until 2025 considers only the Republic of Sakha (Yakutia), Komi and Tatarstan, Krasnoyarsk, Khabarovsk Territory, Nenetsky, Khanty-Mansiysk and Yamalo-Nenets, Chukotka Autonomous Districts, Tyumen, Kemerovo, Irkutsk, Amur, Magadan and Sakhalin regions as priority territories for the spatial development of the mineral resource complex. At the same time, mineral resources development of a number of regions in the Southern, Ural and Siberian macro-regions is ignored. The territorial systems that make up the Ural macro-region have high levels of mineral production and are promising mineral resource centers of the country, which have all the necessary resources and close ties with other regions in processing the extracted raw materials. Key words: interregional relationships; mineral and raw materials complex of RF; spatial autocorrelation; RF Spatial Development Strategy until 2025. Acknowledgements. The research has been carried out in accordance with the research plan of the Laboratory for Spatial Development of Territories, Institute of Economics UB RAS for 2019.
