Fires formed by the high gas protrusion in coal mines are difficult and risky to extinguish during the mine closure process due to the mine's large closed range and underground gas stock. To achieve efficient and safe unsealing, reduce the risk of reignition and gas explosion, and accurately determine the fire extinguishing effect, a dualdrive rapid fire extinguishing technology is proposed.
