Abstract: In view of the complex geological conditions of Fengfeng Group mines, the difficulty of mining the protective layer and the low permeability of No.2 coal seam, Fengfeng Group has improved the comprehensive gas control system from the aspects of organization, work responsibilities, management system, emergency response plan, supervision, inspection and implementation. Fengfeng Group established and improved a gas control system focusing on gas drainage, a management system focusing on “one mine, one policy” and a management assessment system focusing on the implementation of the responsibilities of managers at all levels and the standardized operation of employees at relevant posts. Through the construction of the system and the breakthrough of technology, the mine gas overrun accident has been greatly reduced, and the gas accident has been eliminated, which has laid a solid foundation for the safe and efficient production of Fengfeng Group mines.
