摘要
针对姚桥煤矿通风系统现状,选定12条主要测定线路,采用精密气压计逐点测定法,对其通风系统阻力进行测定,全面掌握了矿井通风系统的阻力分布情况.分析结果表明:姚桥煤矿通风系统阻力分布基本合理,风量能够满足矿井实际生产的需求,矿井通风阻力主要集中在回风段.该阻力测定分析方法对其他矿井阻力测定有着重要要借鉴和指导意义.
In terms of the current situation of Yaoqiao ventilation system,this study selected 12 main measurement lines to measure the ventilation resistance in the ventilation system using precision barometer point test method.Through the measurement,a comprehensive understanding on the distribution of ventilation resistances over the coalmine was achieved.The analysis results show that the distribution of ventilation resistances in Yaoqiao ventilation system is basically rational;the air quantity is able to meet the requirement of actual coal production;and the resistances are concentrated in the return airways.
