Abstract: The study contains data review based on application of major mining and loading equipment in open pit operations. Examples of manufacturing and use of modern unmanned equipment were reviewed. Trends for increasing hydraulic excavators in entire fleet of mechanical shovels operated in open pits were identified. Russian manufacturers of open pit excavators cannot compete with global manufacturers of backhoe hydraulic excavators. Majority of hydraulic excavators operated in the open pits and quarries are made by four largest manufacturers: Liebherr (Germany), Komatsu Ltd. (Japan), Caterpillar Inc. (USA), Hitachi Group (Japan). This study becomes even more relevant as the Russian Government is prioritizing import phase-out, large-scale manufacturing and application of domestic backhoe excavators.
