摘　　要：本文介绍了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,对矿区后建的四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。The paper describes that the mine absolute gas emission increased rapidly when Dafuosi Mine was put into production and that the air velocity in the main return airway exceeded the limit, so that the mine ventilation system could not meet the requirements of the designed production and it was difficult to ensure safety production. After analyzing the state of ventilation system, calculation of resistance, technical proposal for optimization of ventilation was put forward and reconstruction was made. As a result, the production problems were solved, a proper layout of ventilation system suitable for this mine was probed, which is useful for construction of four mines to be built in the in the mine area in the future. It is also useful for management of mine ventilation systems in mining other highly gaseous mines or mines with coal seams prone to self ignition.
