矿井通风系统阻力测定与降阻措施分析

Measurement of Resistance in Mine Ventilation System and Analysis of Resistance Reduction Measures

随着采掘深度不断增加和开采范围日益扩大,井下需风量也随之增大,现有局部通风机能力己不能满足需求,因此需要对矿井总进回风巷道进行全面检查及风路改造,以达到减小通风阻力、提高风机效率的目的。本文主要介绍了矿井通风阻力测定方法及其影响因素,并对其进行降阻措施,为矿井通风系统优化提供参考依据。

With the continuous increase in mining depth and the expansion of mining scope,the air volume required underground also increases.The existing local ventilation fan capacity cannot meet the demand anymore.Therefore,it is necessary to conduct a comprehensive inspec⁃tion and air path transformation of the total intake and return air tunnels in the mine to reduce ventilation resistance and improve fan efficiency.This article mainly introduces the measure⁃ment method and influencing factors of mine ventilation resistance,and takes resistance reduc⁃tion measures to provide a reference basis for optimizing the mine ventilation system.
