Abstract
The role of technological vehicles in the process of open-pit coal mining is difficult to overestimate. The share of transportation costs in the total cost of production is more than 50% and with the complication of mining conditions can increase significantly. In such conditions, the technical and economic indicators of the entire mining enterprise depend on the efficiency of the operation of quarry dump trucks. The use of lean manufacturing principles by enterprises is aimed at constant analysis of the efficiency of production processes and their improvement, since this concept itself is reduced to minimizing all losses. For quarry dump trucks, as expensive technological equipment, the most important indicator of the efficiency of use is the share of working time. Any loss of working time leads to a significant reduction in it. This article provides a consistent analysis of the structure of machine time losses as a way to assess the efficiency of operation of dump trucks at coal mines.
