Research on the Prevention and Control Technology of Low Oxygen in The Upper Corner of Fully Mechanized Coal Mining Face in Daliuta Coal Mine
Year: 2024
Type: article
Abstract: In response to the problem of low oxygen in the upper corner of the return air of the 52506 fully mechanized mining face in Daliuta Coal Mine, the impact of atmospheric pressure and temperature changes on the low oxygen in the upper corner of the 52506 fully mechanized coal mining face is analyzed, and the source and cause of the low oxygen gas in the upper corner of the 52506 fully mechanized coal mining face are analyzed from multiple perspectives. A comprehensive treatment method is adopted, including installing windshields and air guide boards at the head and tail ends, joint sealing and leak-repairing at the ground and underground levels, sealing the adjacent goaf communication alleys, pressure ventilation, negative pressure suction, monitoring and control management, etc. This method solves the problem of low oxygen in the upper corner of the 52506 fully mechanized coal mining face.
