五圩矿通风系统技术改造的实践

Technical transformation of ventilation system in Wuxu Mine

针对五圩矿通风系统存在通风线路过长、风流内部短路、漏风严重、采场通风条件差等问题,采取了降低风阻、缩短风路、封闭旧巷道等技术改造措施,使井下通风条件明显改善,通风效果达到了安全生产要求。

In addressing the existing problems of tong external line and short internal ventilation circuit, serious air leaking-out, poor ventilation condition and others in the ventilation system of Wuxu Metal Mine, technical transformations such as lower ventilation resistance, shorter ventilation line and closure of used tunnel were con ducted with the remarkable improvement of the underground ventila tion conditions and the ventilation effect meeting the requirement in safety production.
