Summary:
Kocjancic is an underground coal mine. The mine operates a single mechanized mining unit (MMU) in the Lower Kittanning coal seam (bituminous) with an average mining height of 40 inches. The mine operates one production shift, five days a week, using the room and pillar mining method.
The mine operator extracts coal using a continuous mining machine (CMM), which is then transported by mobile bridge conveyors to the dumping point. The mine operator uses a belt conveyor to transport coal to the surface. The mine uses self-propelled, rubber-tired personnel carriers and scoops to transport miners and materials in and out of the mine.
