Abstract:

Purpose. The substantiation of diagnostics methodology for technical state of reinforcement in vertical shafts with broken geometry and renewal of the exploitation safety of mine winding plants.

Methodology. Relationship between parameters technical state of the system elements and parameters of exploitation safety of mine winding plants is established. Methods of instrumental measurement and calculation of the system diagnostics parameters are substantiated.

Findings. The methods of choosing maintenance and repair operations and correcting operating parameters of system elements, providing safe exploitation of mine winding plants in shafts with broken geometry in the specified technological modes, are grounded.

Originality. The article specifies the dependence of dynamic parameters which determine the risk of emergency danger on the parameters of the technical state of separate links of winding plant In the article on the base of complex research studies, regarding the structure of the mine winding plant as an iterative, multimass discrete-continual system with plural deviations of operating parameters from the legitimate project values. On the base of findings the methodology of the instrumental diagnostics of the system in the operating mode and the emergency braking mode, as well as methods of reducing emergency danger level while increasing the plant work intensity are grounded.

Practical value. The methods of apparatus control and determination of diagnostic parameters of winding plants under production conditions, methods of targeted choice of repair operations providing transition of plants from the potentially dangerous operating state into safe technical state are grounded.
