The Pennsylvania mining complex, which includes the Bailey Mine, the Enlow Fork Mine and the Harvey Mine, has extensive high-quality coal reserves. The Pittsburgh No. 8 Coal Seam is a large contiguous formation of uniform, high-Btu thermal coal.

The design of the Pennsylvania mining complex is optimized to produce large quantities of coal on a cost-efficient basis. The PAMC is able to sustain high production volumes at comparatively low operating costs due to, among other things, its technologically advanced longwall mining systems, logistics infrastructure and safety. All of the PAMC's mines utilize longwall mining, which is a highly automated underground mining technique that produces large volumes of coal at lower costs compared to other underground mining methods. The PAMC typically operates 4-5 longwalls with 15-17 continuous mining sections.

Bailey Mine
The Bailey Mine, operated by Consol PA Coal Co, is located near Graysville, Greene County, Pennsylvania. The mine is opened by eight shafts and one slope into the Pittsburgh coal seam which averages 69 inches in thickness. The mine produces coal three shifts per day six days per week.

Five continuous mining sections and two longwall sections produce an average of 24,987 tons of coal daily. Coal is transported from the face areas to the section loading point by a chain conveyor on the longwall sections and by shuttle cars on the continuous mining sections. Coal is then discharged onto a series of belt conveyors and transported to the surface preparation plant. Clean coal is transported by unit train to various customers.

The Enlow Fork Mine
Miners access the Enlow Fork Mine by three shaft openings and a slope opening into the 96-inch Pittsburgh bituminous coal seam. The mine is ventilated with nine air shafts, all with exhausting mine fans. The mine liberates 11,564,125 cubic feet of methane every 24 hours. The mine has nine mechanized mining units (MMUs) producing 42,000 tons of raw coal daily. Two MMUs are longwall sections and seven are continuous mining machine (CMM) sections. After coal is extracted from the CMM face, it is transported by shuttle cars or ram cars to the section loading point. Belt conveyors transport coal to the surface. Rail-mounted diesel locomotives and personnel carriers transport miners, materials, and supplies between the entrances and work area.

The central preparation plant is connected via conveyor belts to each of the PAMC's mines and cleans and processes up to 8,200 raw tons of coal per hour. The PAMC's on-site logistics infrastructure at the central preparation plant includes a dual-batch train loadout facility capable of loading up to 9,000 clean tons of coal per hour and 19.3 miles of track linked to separate Class I rail lines owned by Norfolk Southern and CSX, which significantly increases the PAMC's efficiency in meeting its customers' transportation needs.
