Abstract

Selection of the rational mining equipment fleet for efficient operation at minimal costs and enhanced performance, reliability and safety is one of the most important tasks in development of any deposit. The wheel loaders available in mines in amount of one or two machines are important and significant production objects. Considering substantial procurement, maintenance and operation investment, selection of a rational machine model is a topical objective. The common practice of shaping the fleet of loaders in a mine shows that the decision on procurement of a machine model under conditions of deficient operating experience is made based on a managerial solution after the comprehensive review of performance specifications submitted by mining and processing plants, commercial proposal made by manufacturers and the global experience in employing high technical level equipment. The article off ers an approach to comparative assessment of performance characteristics of wheel loaders, including analysis of operating data and reliability of the machines, evaluation of fuel saving and production output, as well as economic efficiency and assessment of operational level of wheel loaders. In aggregate, the considered characteristics are the selection criterion for wheel loaders and allow reasonable approach to optimal structuring of mining machinery fleet. The investigation results have been discussed and approved for application at ALROSA company.
