The ground coal is picked up by an air stream emerging the mill through a port ring on the periphery of the grinding table. • Air entering through the port ring creates a fluidizing zone in which "heavy material" (mill rejects—MR) such as rock falls through the port ring into the air plenum below the grinding table and is ejected from the mill through the MR system.

A highwall mining system is typically used for surface mining. It consists of a remotely controlled continuous miner to extract coal from exposed seams by driving a cutter module into a coal seam under a high wall. The coal is mined by the action of the cutterhead that is raised and lowered to dig out the entire height of the coal seam. Hoppers
