| Field of use: The
dump heap MHD 4400x50 is designed to work in the open pit mining. The machine can be
used for sterile dump taken over from the roller of the stacker. In the conveyer flitting
or in other necessary cases, the machine may discharge successively the dump or the coal
from the upriver conveyer, in one or several conveyors, in the technologic flow of the
pit.
