  • Ventilation/Gas Control Introduction underground COAL

    Ventilation/Gas Control. The ability to provide adequate ventilation to a longwall panel can be a major factor in the success of an installation, especially in gassy conditions. Most gassy mines now use some degree of gas predrainage of the seam being worked which greatly reduces the gas to be dealt with during longwall extraction.
