摘　　要：大佛寺煤矿投产后因矿井绝对瓦斯涌出量急剧增加,主要进回风巷风速超限,矿井通风系统不能满足设计产量的需求,更难以保证安全。实施通风系统现状分析、阻力计算、改造等优化技术方案后,解决了生产问题,探索出适合该矿区的通风系统布置方式,对矿区后建的4对矿井和其它开采高瓦斯易自燃煤层的矿井通风系统管理具有借鉴意义。Because the gas discharge increased sharply after Dafosi coal mine brought into production, and the air velocity in main intake and return airway were over the limit, the ventilation system could not meet the demand of production. It was difficult to ensure safety production. After the situation analyzing, drag calculation, improvement of ventilation system, the production problems were solved, and the suitable ventilation system was sought out, and which provided reference for ventilation system management and later shafts construction.
