The purpose of this topic is to analyze the basic operating conditions of excavators such as a mechanical shovel, which have (compared to other types) the maximum application at our mining enterprises; using the example of Mounts Magnitnaya, Vysokaya and Elenovskie quarries, study, analyze and generalize the experience of excavator operators; establish ways of the most rational organization of excavation work. The above reasons for excavator downtime and its unproductive use are the most important and undoubtedly overwhelmingly removable. If we turn to other reasons, they can be exhausted by the following list: refueling and lubrication of the excavator, routine repairs, emergency repairs, cable re-hooking, cable change, bucket cleaning, path preparation, lack of energy, lack of spare parts, lack of contact network, change of crews , others. A significant part of these reasons can also be eliminated by proper organization of the entire mine economy, coherence of all workshops and responsible management and supervision of engineering and technical personnel, representing a reserve for increasing the productivity of the excavator.
