煤矿井下通风系统通风阻力测定分析

Measurement of Ventilation Resistance of Underground Ventilation Systems in Coal Mines

高质量的通风是煤矿安全生产的基础,但是随着开采难度的加大,煤矿的通风阻力增大,实际的通风效率降低,导致生产安全性无法得到保障。为了降低通风阻力,在介绍通风系统组成和结构的基础上,详细阐述了通风阻力测定的方法、线路及测点布置等,分析了造成通风阻力增大的原因及降低通风阻力的措施,为优化通风系统提供参考。

High-quality ventilation is the basis of coal mine safety production,but with the increase of mining difficulty,the ventilation resistance of coal mines increases,the actual ventilation efficiency decreases,resulting in production safety can not be guaranteed.In order to reduce ventilation resistance,based on the introduction of the composition and structure of the ventilation system,this paper elaborated in detail on the method,line,and measurement point layout of ventilation resistance measurement,analyzed the reasons for the increase in ventilation resistance and corresponding measures to reduce ventilation resistance,providing reference for optimizing the ventilation system.
