摘　　要：结合八矿丁一采区实际情况提出一系列矿井通风系统优化与改造,通过方案实施,丁一风井总风量由原来的9880m3/min提高到现在的12230m3/min,确保了矿井由一水平采区向二水平采区过渡时期的安全生产,缓解满足了高突工作面的用风需求,降低了采掘工作面的瓦斯浓度。成功地解决了平煤股份八矿在大采深、多煤层群、复杂通风系统生产条件下,矿井两个水平同时开采风量紧张的问题。In combination with the practical situation of D1 mining area under No.8 coal mine, the paper puts forward a series of mine ventilation system optimization and reformation. After its implementation, the total air volume of D1 mining area is increased from 9,880m3/ min to 12,230m3/min; it ensures the production safety in transition from No.1 horizontal mining area to the No.2 horizontal mining area, and meets the requirements for the wind need at high working face, reduces the gas concentration of mining working face. It resolves the problems of mining air volume -need at two horizontal mining area at the same time under the condition of large mining depth, multi-coal seam group and complex ventilation system production conditions.
