Assessment Possibilities of the Quality of Mining Equipment and of the Parts Subjected to Intense Wear

The equipment in underground mines provides a continuous production flow, depending on the way their quality is preserved during operation. TR-7A scraper conveyer subassemblies, which function Jiu Valley coal basin and are subjected to abrasion wear, showed high failure frequency (chains, chain elevators, driving turning drums), as well hydraulic couplings certain electric of same machinery. data collected following at work allowed parameters be determined that characterise reliability maintainability above-mentioned components, modes, effects. Using calculation methods, interpretation results has been facilitated, with view reducing maintenance costs obtaining an 80% for components most failures, case conveyer.
