Arch Coal (ARCH) operates five mining complexes in the Appalachian region that produce metallurgical coal. Metallurgical coal is also known as coking coal and is used in steelmaking. Carbon content, the composition of the non-carbon volatiles, and other chemical constituents are critical characteristics of metallurgical coal.
Lone Mountain Complex
Located in Kentucky and Virginia, Lone Mountain Complex is an underground mining complex that covers ~54,000 acres. It extracts PCI (a type of coking coal) and high-quality thermal coal. The complex had ~9.5 million tons of proven and probable reserves on December 31, 2016.
The complex consists of three underground mines operating six continuous miner sections. The coal produced at these mines is processed through a preparation plant capable of processing 1,200 tons per hour. This coal is transported to customers via the Norfolk Southern (NSC) or CSX railroads.
Mountain Laurel Complex
Mountain Laurel Complex is an underground and surface mining complex located on ~38,200 acres in West Virginia. Underground mining operations at the complex extract High-vol B metallurgical coal and thermal coal. The complex had ~13.2 million tons of proven and probable reserves on December 31, 2016.
The complex consists of one underground mine operating a longwall and three continuous miner sections, a preparation plant, and a loadout facility. The coal is processed through a preparation plant capable of processing 2,100 tons per hour. This coal is shipped to customers via the CSX (CSX) railroad system.
Beckley Mining Complex
A 19,500-acre complex in West Virginia, Beckley Mining Complex extracts high-quality, low‑volatility metallurgical coal. On December 31, 2016, Beckley Mining Complex had ~24.5 million tons of proven and probable reserves. The preparation plant has a throughput capacity of 600 tons per hour.
The processed coal is transported to customers via CSX railroad. The loadout facility can load a 10,000-ton train in less than four hours.
Sentinel Mining Complex
Sentinel Mining Complex consists of one underground mine, a preparation plant, and a loadout facility located on ~25,500 acres in West Virginia. Its mining operations currently extract High-vol A metallurgical coal, which is processed and shipped by CSX rail to customers. On December 31, 2016, the complex had ~9.8 million tons of proven and probable reserves.
Leer Mining Complex
Leer Mining Complex covers 78,700 acres in West Virginia. It had ~38.3 million tons of coal reserves on December 31, 2016, which is owned by Arch Coal, and it extracts High-vol A metallurgical-quality coal.
All the production is processed through a 1,400 ton-per-hour preparation plant and is loaded on the CSX railroad. A 15,000-ton train can be loaded in less than four hours.
