Summary:
The primary coal seam mined is the Lower Kittanning (bituminous).
Summary:
The Kocjancic mine is an underground mine owned and operated by the Rosebud Mining Company, located in Jefferson County, Pennsylvania. Miners enter the mine, which is in the Lower Kittanning (bituminous) coal seam, via 3 slopes. The mine is ventilated with two intake slopes and one exhaust fan.
Coal is extracted by a continuous mining machine (CMM) and then transported by mobile bridge carriers (MBC) and bridge conveyors, which are attached to the rear of the mining machine. Coal is then transported over a system of conveyor belts to the surface. Rubber-tired diesel and battery-powered scoops and rubber-tired battery-powered personnel carriers are used to transport materials, supplies, and miners.
