余吾矿通风系统阻力测定及其优化改造

Resistance Measurement of Ventilation System and Its Optimization Modification in Yuwu Mine

针对余吾矿通风系统现状,选取2条主测路线,对其进行通风阻力技术测定,得到实测通风参数并对其进行风网解算验证,掌握了矿井通风系统运行状况,分析找出了该矿通风系统目前存在问题。结合矿井的采掘部署和风量需求分配情况,提出了切实可行的优化改造方案,为进一步改善矿井通风管理水平、提高经济效益提供强有力的支撑。

According to current situation of ventilation system of Yuwu Mine,selecting two main test routes,the ventilation resistance of mine ventilation system was determined,the measured ventilation parameters were obtained and verified through ventilation network solution,the operation status of mine ventilation system was grasped; the current existing issues were identified. And the feasible optimization scheme was proposed combining with mining deployment and air volume demand distribution,which provides strong support for the improvement of mine ventilation management level and economic efficiency.
