Abstract

Currently, the technology of works at the operating open pits in terms of development of the coal-bearing zone is usually conducted by horizontal layers. As the main excavation and loading equipment are most often used mechanical (rope) shovels and backhoes, less often direct hydraulic shovels. Also, joint work of these machines in any combinations is used. But the justification of the parameters of these complexes both in the projects of coal mining enterprises and in scientific articles is covered insufficiently. This article presents the basic provisions of the methodology for selecting excavation and loading equipment for the development of coal-bearing zones at opencast mines, describes the principles of tools to determine the capacity of the excavator bucket, used for outpacing excavation of coal.

Keywords
