They seem to use both anthracite and coke. I know the used the hard coal for firing the furnaces and plant heat. I don't know about the coke, may be it is added to cement mix to make clinker. The current plant fires the kilns and furnaces with natural gas, I think, any coal shipments they get today is brought in by truck.
