Abstract
The definition of technological complexes of opencast mining is given. Their systemization is done. It shows that in the open cast mining are used the following technological complexes (TC). Simple systems complexes: excavator, bulldozer, scraper, drainage and hydro-mechanized technological complexes. At these TC the excavation and movement of rock mass is realized by a single machine. Two-component complexes: excavator-rail, excavator-automobile, excavator-conveyor, excavator-console, excavator-dump-bridge technological complexes. At these TC the excavation and loading of mining mass is produced by one machine - an excavator (shovel, bucket wheel, chain), and its transportation is carried out by another machine (different type of transport). Three-component complexes: excavator-automobile-rail, excavator-automobile-conveyor, excavator-automobile-skip, excavator-automobile-crate,excavator-automobile-of-different-types technological complexes. At these TC the excavation and loading of mining mass is produced by one machine (excavator), and its transportation is realized by two types of transport.Examples of their implementation in the quarries of Kazakhstan and Uzbekistan are given. The comptetive of the three-component technological complexes of deep pits is proved.
