First of all, it is necessary to ensure that the air volume at each air-using location is sufficient to prevent gas accumulation. Then there is high-intensity gas extraction, multiple drillings, dense drillings, and strict extraction. Regional gas control includes mining of protective layers and gas extraction of the coal seam (through layers, along layers), and local advanced extraction and discharge drilling. Through extraction, the gas content in the coal seam can be reduced, thereby reducing
