柏杖子金矿通风系统改造工程设计及应用

摘要

The establishment and improvement of mine ventilation system is one of the key factors to achieve safe mining production.In view of the problem of extending mining depth that leads to lengthy ventilation lines and lack of fresh air flow,the paper optimizes and renovates the previous ventilation system,arrives at an opposite-side two-winged pump-out ventilation system with existing vertical shaft and new comprehensive shaft as in-flow air shaft.The designing process of the ventilation optimization and renovation project is described in detail.The project achieves good outcome.%矿山通风系统的建立和完善是实现矿山安全生产的重要条件之一.针对柏杖子金矿开采深度不断延伸,通风线路增长、新鲜风流不足等问题,对原有通风系统进行优化改造,形成了原竖井和新混合井作为进风井,两翼对角抽出式通风系统,并详细介绍了通风系统优化改造工程设计过程,工程应用取得了良好的效果.
