高原特长瓦斯隧道通风排烟设计探讨

摘要

Plateau super-long gas tunnel ventilation and smoke exhaust should be designed in such a way so as mainly to solve the systematic relation between flat guide, inclined shaft, and main hole. The study, by flow calculation, optimization of ventilation scheme, selection of ventilation equipment and other measures, solves ventilation circulation between fiat and inclined shaft, therefore, it ensures the fresh air supply near the tunnel face and construction safety, and improves the per- sonnel, machinery equipment efficiency, and speeds up the construction progress.%高原特长瓦斯隧道通风排烟设计,主要是解决平导、斜井、正洞之间的通风系统关系,通过供风量的计算、优化通风方案、精选通风设备等措施,解决平导与斜井之间通风排烟循环问题,从而保证了掌子面附近的新鲜空气的供给量,形成了有序的通风排烟循环系统,提高了人员、机械设备的工作效率,加快了施工进度,确保了施工安全。
