摘　　要：矿井通风阻力是反映矿井通风系统工作状态的重要指标。在矿井开采初期,矿井通风阻力较小,而随着矿井开采的进行,通风网络变得复杂,矿井的通风阻力增加。因此,必须采取有效的方法降低矿井通风阻力,提高矿井通风的有效性。简要分析了矿井通风系统的局部阻力和全局阻力,并在此基础上提出了一些降低矿井通风阻力的方法。Mine ventilation resistance is an important index to reflect the working state of mine ventilation system.In the initial stage of mining,the ventilation resistance of the mine is small,but with the development of mining,the ventilation network becomes complex,and the ventilation resistance of the mine increases.Therefore,effective measures must be taken to reduce the resistance of mine ventilation and improve the effectiveness of mine ventilation.This paper briefly analyzed the local resistance and the global resistance of the mine ventilation system,and based on this,put forward some methods to reduce the mine ventilation resistance.
