Introduction. Winding wire rope, being a flexible element capable of carrying high tensile load, is widely
used in modern hoisting equipment. Now it is hard to imagine the majority of important sectors of economy
without the well-used hoisting wire ropes. This primarily applies to construction and mining where wire
rope is widely used in hoisting equipment.
Research aim. Based on scientific discoveries in mine wire ropes design made by the Russian scientists,
the present research aims to determine the main parameters affecting mine wire rope safe operation.
Methodology. Hoisting wire ropes in service, operating in the conditions of free suspension, are subject to
significant unwinding in tension in deep hoisting shafts, as a result, spiral elements lay angles of wire rope
change and cause a geometrically nonlinear nature of strains. Calculating the radius and angle of waviness
using an inflexible calculation model results in low accuracy. The present research determines the
parameters affecting wire rope safe operation; nonlinear theory of wire ropes calculation has been applied
making it possible to improve the reliability and durability of the mine wire rope.
Results. The present article defines and provides support for the parameter affecting the safe operation of
mine hoisting wire ropes. The equation of the radius of waviness is derived through nonlinear dependences.
The quantitative value of the permissible radius of waviness is specified.
Summary. The obtained formulae allow to determine the permissible value of the radius of waviness
wherein future safe operation of mine wire rope is possible. Due to the formulae which determine the
permissible value of the radius of waviness, the recommendations given in this article will improve
the security of steel mine wire rope operation.

Key words: wire rope; strains; permissible value; waviness, lay angle; theory of wire rope.

Introduction. More complex mining and geological conditions of solid minerals extraction during
underground development result in the loss of work efficiency. The solution to the problems is in the
creation of shortwall extraction technologies based on the swivel scraper conveyor operation.
Research aim. Based on the analysis of the single-chain traction unit operation situated in the centre
of pans, research aims to provide steady movement of scrapers at ramp’s turn up to 90° in the bedding
plane, develop the constructive scheme of a conveyor which meets the accepted work technologies.
Methodology. System analysis of structures is carried out together with the traction unit movement study,
based on the simulation with the method of dynamic equations linearization in Adams, with the analysis
of data from swivel conveyor prototypes testing.
Results. The model and the movement mechanism of the tension unit with scrapers along the pin-connected
pans at an angle up to 15° have been worked out and substantiated; constructive schemes of units for
the turn zone have been identified, ensuring the stability of tension unit movement and the retention of the
transported material within the limits of the rod. It has made it possible to develop the specification
of requirement for the conveyor test model design, calculation and testing, and specify its scope.
Summary. The possibility of creating efficient models based on the linearization of dynamics equations in
Adams package taking into account oscillations within the system. Features of scrapers movement in the
turn zone and the mechanism of oscillations suppression by means of a “pair of forces” at the scraper
of a traction unit have been identified. The system is effective under the angle of the turn up to 15ο for each
pan. Constructive schemes have been identified for a swivel scraper conveyor that ensure the steady
movement of scrapers and overlap the gaps at the turns of the sections, with an elastic segmental reflector.

Key words: modeling; scraper conveyor; turn zone; linearization of dynamics equations.
