晋普山煤矿通风系统阻力测定与分析

Measurement and Analysis of Resistance in Ventilation System of Jinpushan Mine

矿井通风系统阻力测定是煤矿通风技术管理的重要内容,阻力的大小直接影响矿井的通风效果,笔者介绍了矿井通风阻力测定常用的几种方法,分别评述了其优缺点及适用条件,并根据晋普山煤矿通风系统实际情况,选用基点法对其通风阻力进行了测定,全面、准确地掌握了全矿井通风阻力分布情况,为今后进行通风系统调整,提供了有参考价值的基础数据资料。同时依据测定结果,对晋普山煤矿通风系统进行了合理分析。

The resistance measurement of ventilation system in mine is an important content in ventilation management. The magnitude of ventilation resistance directly affects its efficacy. Some methods commonly used in ventilation resistance measurement are introduced, their advantages and disadvantage as well as their feasibilities are discussed respectively. Basic point method is se- lected to measure the ventilation resistance according to actual situation of Jinpushan mine. Through measurement the resistance distribution in whole ventilation system is known providing valuable data from which rational analysis could be made.
