Mine Life2045
Warrior Met is a large-scale, low-cost producer and exporter of premium quality met coal, also known as hard coking coal (“HCC”), operating highly-efficient longwall operations in our underground mines based in Alabama, Mine No. 4 and Mine No. 7.

Warrior Met CBA contract with the UMWA expired on April 1, 2021, and the UMWA initiated a strike that continues today. The company continues to negotiate in good faith to reach a new union contract. As a result of the strike, Company initially idled Mine No. 4 and scaled back operations at Mine No. 7. In the first quarter of 2022, the Company restarted operations at Mine No. 4.

Deposit Type

  • Sedimentary


Summary:

Deposits Sediments of the Upper Pottsville Mary Lee coal zone are Lower Pennsylvanian in age and comprised of cyclic sequences that include sandstone, siltstone, shale, and coal. Located within the middle of the Black Warrior Basin stratigraphic sequence, the Mary Lee and Blue Creek horizon is situated below drainage throughout the Property and is accessed by shafts. The lithologic variability of the Mary Lee - Blue Creek sequence and enclosing strata is discussed below: > The New Castle seam is present approximately 20 to 50 feet above the Mary Lee seam. > Lithologic composition of the roof strata varies throughout the Property but consists primarily of a coarsening-upward sequence of shale or sandy shale, with occasional sandstone channels located within the immediate or main roof of the Mary Lee seam. > In areas where sandstone occupies the immediate roof of the Mary Lee seam, seam scouring may locally occur. Where sandstone channels are present within 4 to 6 feet above the Mary Lee (roof bolt horizon), there is potential for increased drawrock conditions and roof instability beneath the sandstone/shale contact. > Areas, where the combined thickness of the Mary Lee - Blue Creek horizon is less than a minimum continuous miner cutting height (7.0 feet), are shown, which as a result, roof (and/or floor) strata are expected to be excavated as out-of-seam dilution (050). > Thickness and composition (shale, carbonaceous shale, fireclay, and sandy shale) of the stratum ........


Mining Methods

  • Longwall
  • Continuous


Summary:

Due to its coal reserve and seam characteristics, the Property utilizes longwall mining methods with continuous miner units to support the longwall production unit.

Run-of-mine coal is transported to the surface via a skip system which transports coal to the surface vertically. Adjacent to the skip shaft is a service shaft for the transportation of workers, supplies and equipment to the coal mine. Warrior Met is nearing the completion of a new portal site, closer to active faces and future mining reserve areas, which is currently being utilized in a partial capacity prior to serving longwall needs. Bleeder shafts are installed at each longwall district.

Operating at approximately 2,000 feet below the surface, the Mines No. 4 and No. 7 are two of the deepest underground coal mines in North America. The met coal is mined using longwall extraction technology with development support from continuous miners.

Mine No. 4 has had multiple improvements to the infrastructure by adding new portal facilities in 2019 and 2021. The Mine No. 4 North portal development is expected to be completed in 2023. These facilities have helped to decrease travel time to the active sections, as well as improving the safety of the miners by having shafts closer to the main work areas.
