Mathematical models have been developed for the degassing of roofing coal packs discharged into treatment faces when mining powerful flat coal seams with one face. It was shown that when a powerful coal seam is excavated to full capacity with one face with the release of a sub roofing pack, methane release from the sub roofing pack of a disturbed structure will be formed according to the laws of gas motion in fractured-porous sorbing media.
