通过对三水平通风系统分析,提出三水平通风系统优化方案,实施后缩短了通风流程,提高了三水平通风能力,降低了矿井通风阻力和通风费用。%This article analyzes the third-level ventilation system and proposes the optimization method. After putting the optimization method into practice, the ventilation process has been shortened, the third-level ventilation ability has been improved, and the ventilation resistance and cost has been reduced.
