CANONSBURG, Pa., Jan. 16, 2025 /PRNewswire/ -- Core Natural Resources, Inc. (NYSE:CNR) today announced that it was taking steps to temporarily seal the Leer South mine's active longwall panel in order to extinguish isolated combustion-related activity there. Based on its collaborative, ongoing discussions with regulatory authorities, Core believes Leer South will be able to resume development work with continuous miners within the next three months, and to resume longwall mining mid-year.
"On behalf of the Core management team, I want to commend Leer South personnel for their exceptional efforts in managing a challenging situation safely and effectively, and I want to thank the regulatory agencies for their great support during this process," said Paul A. Lang, Core's chief executive officer. "While we are disappointed that we may be losing around two quarters of longwall production at Leer South, we are confident we are taking the right steps to protect the mine, mining equipment, and infrastructure. We have a good understanding of where the combustion-related activity is occurring and are confident that this limited activity does not currently present a threat to the longwall equipment. Working closely and cooperatively with federal and state officials, we plan to temporarily seal the active longwall panel and apply water and nitrogen to extinguish this combustion-related activity, which should lead to the most expeditious resumption of mining."
The re-entry process will be multi-phased, beginning with the construction of ventilation controls followed by the resumption of continuous miner development. As a result, the company expects to advance development work on future longwall panels, which should enable the longwall system to operate in a highly efficient manner in the year's second half.
"Looking ahead, the Core operations team has already initiated efforts to help ensure that we avoid such incidents in the future," said George J. Schuller Jr., Core's chief operating officer. "We are confident that there are steps we can take – in the areas of monitoring, degassing, and the installation of proactive mitigation systems – that should enable us to avoid future outages."
