Coal Age: Seal Construction at the Cardinal Mine

Moving from the No. 11 to the No. 9 seam, Warrior Coal reclaims assets and seals old works

“From a regulatory point of view, only a limited number of 120-psi seal options have been approved by the Mine Safety and Health Administration (MSHA) that can be constructed in heights that are approximately 30 ft. After discussing plans with seal contractors and MSHA, Warrior Coal selected the Micon 120-psi Main Line Hybrid II Seal. Based upon the range of height expected, the large seal according to the Micon seal specifications would be 10 ft to 12 ft thick.”
