摘　　要：矿井通风系统总阻力是影响通风效果的主要因素,对影响矿井阻力的因素进行归纳总结,分析矿井阻力测定方法,将测定得到的数据与计算得到的数据对比可知,测量误差在5%以内,数据是可靠的。基于通路法对矿井通风系统网络结构进行优化,优化结果显示,优化后系统的通风量增加,矿井通风总阻力减小,可更好地实现降阻减压的效果。The total resistance of the mine ventilation system is the main factor affecting the ventilation effect.The factors affecting the mine resistance are summarized,and the measurement method of the mine point resistance is analyzed.By comparing the measured data with the calculated data,the measurement error is within 5%,so the data is reliable.The network structure of mine ventilation system is optimized based on the access method.The optimization results show that after optimization,the ventilation volume of the system increases and the total resistance of mine ventilation decreases,which can better achieve the effect of reducing resistance and decompression.
