显德汪矿通风系统优化改造

Optimization and Transformation of Ventilation System in Xiandewang Mine

针对显德汪矿通风系统出现的一些问题,对通风系统进行了详细的测定实验。通过调查与分析,发现通风系统风网结构不尽合理,风机能力互相匹配不当,矿井回风路线过长、通风阻力偏高、多处局阻大、风流不畅,并制定了系统改造方案,介绍通风系统改造过程。实践表明,改造取得了良好的效果。

Based on some problem of ventilation system in Xiandewang Mine, ventilation system was measured by experiment. Through investigation and analysis, unreasonable wind ventilation system network structure was found out, improper fan ability matched each other, with long mine air return route, high ventilation resistance, large resistance in partial area, bad aircurrent, system transformation scheme was settled, the ventilation system transformation process was introduced, with good practical effect.
