To effectively manage the outburst coal seam gas, Dashe Mine of Fengfeng Group has implemented comprehensive strategy of “to protect if possible, to extract if needed” on the difficult situations of deep-depth in mining, complicated geological conditions, severe governance on gas-proof. It has cultivated a series of comprehensively protection technology on applicable mining gas in parameters setting of coal seam gas, developing covering layer, eliminating regional conflicts, conducting extraction on non-protectively recoverable area, optimizing ventilation system, implementing real-time monitoring and so on, all of which have effectively elevated the gas control capacity, providing safeguard to the building of mines with safety, efficiency and environmental-protection.
