吕家坨矿通风阻力研究

Study on Ventilation Resistance of Lyujiatuo Mine

通过对吕家坨矿基本情况的了解,根据现场数据及相关理论依据,分析了最大通风阻力路线。结果表明:降低-600东大巷、-425回风山两段、-125西大巷这3段通风阻力是降低整个矿井通风阻力的关键所在。确保通风优化方案的有效性,为同类企业加强通风系统优化提供了参考。

The maximum ventilation resistance route was analyzed based on the understanding of the basic situation of the Lyujiatuo Mine and the analysis of the field data and relevant theoretical basis. The results show that total ventilation resistance of the mine can be decreased by the reduction of ventilation resistance of -600 east alleys, -425 two sections of return air mountain and -125 west alleys. Three-stage ventilation resistance is the key to reduce the ventilation resistance of the entire mine. It can ensure the effectiveness of the ventilation optimization program and provide a reference for the optimization of ventilation systems of similar enterprises.
