Core Natural Resources（代號：CNR）於2026年5月19日提交8-K申報文件，披露旗下Wolf Run Mining LLC位於西維珍尼亞州巴伯縣的Leer South煤礦，於5月13日收到美國礦山安全與健康管理局（MSHA）根據《聯邦礦山安全與健康法》第107(a)條發出的「立即危險」命令。該命令指出，檢查人員在礦區某處發現甲烷濃度升高。管理層隨即與MSHA協調，命令於5月14日凌晨被終止。經進一步討論後，MSHA於5月18日正式裁定，從未存在立即危險，並撤銷該命令。事件未造成傷亡或停產，對公司運營及財務狀況無重大影響。投資者毋須過度憂慮，此為煤礦業常見安全檢查流程，且結果已獲澄清。
