4 CONCLUSION
Thus, it proved that it is impossible to formalize the work of complex-mechanized face based
on the use of continuous or discrete final description of the processes of loading, movement
and unloading of coal by the technological equipment of the excavation site.
A mathematical model of the complex—mechanized face based on the separation of the
processes of loading, movement and unloading of coal technological equipment of the excavation site. The presented model adequately describes the main technological processes at the
excavation site.
The presented mathematical model of formalization of the main technological processes
taking place at the excavation site—breaking, loading, moving and unloading of coal can
used to determine the effective modes of operation of complex-mechanized face, in order to
achieve maximum productivity of the excavation site and to ensure trouble-free operation of
the installed equipment.
