Driving ventilation in long distance large section face was always a difficult problem for coal mine management. Gas emission law in 2203 driving face was analyzed and calculated in this paper, and ventilation scheme with “four fans, double power supply, two air pipes” was put forward. The result showed that reliability of ventilation system in driving roadway was improved, gas override was prevented, and efficient driving construction was ensure. Therefore, this scheme had good economy, which provided reference for similar mines.
