Coal preparation plants

Excavated coal is transported from the mine straight to the coal preparation plant. There, except classifying, is coal also prepared for sale. Coal is transported by belt conveyors between individual operations by belt conveyors. The control system of the individual sections of belt conveyors is responsible for conveyor operation, monitoring operational and failure limit states and establishing and operating the transport route. Besides visualisation panels which are part of each section of belt conveyor and are used for monitoring values and service purposes, there is also a great centralised visualisation which is placed at the control room and it’s intended for entire plant. The great centralised visualisation provides dispatchers an overview about states of individual sections and also allows them to give operation commands for particular control system.
