The article presents the experience gained by Lebedinsky GOK (Mining and Processing Plant) in betterment of repair maintenance of equipment. Good working condition of equipment is ensured by the reliable functioning of the scheduled maintenance system and is backed by the execution of administrative and technical measures. In 2013–2016 Lebedinsky GOK has rearranged the maintenance service and combined it with the subsidiary production units, which earlier performed dedicated repair operations. That allowed centralization of the equipment maintenance control, more efficient deployment of repair staff and, as a result, cost-saving and higher productivity of maintenance work. The organizational structure of the service has become more compact: it has been headed by the Deputy Chief Engineer on Maintenance of Lebedinsky GOK, with the two leading specialists underneath – Chief Mechanic and Electrical Supervisor to head the related production units. The maintenance service rearrangement run concurrently with the activities aimed at reduction in duration and improvement of quality of repair works with a view to minimizing downtime of equipment. Eventually, a stable trend to cutting unscheduled downtime due to equipment failure has been achieved. The repair technology innovations have produced a significant effect, too. The labor input of the maintenance service staff allows Lebedinsky GOK to hold the leading positions in the world market in terms of the product quantity and quality.
