红岭矿通风系统优化设计

Optimization Design of the Ventilation System in Honling Mine

根据红岭矿开拓系统和通风系统的特点,利用通风系统三维动态模型、通风网络优化、机站优化、风机优选等技术措施解决矿井总风量不足、中段风量分配不合理、采区新风污风循环等诸多问题。通过Ventsim三维通风动态仿真模拟软件解算结果表明:矿井通风系统总风量由优化前的77.7 m3/s提高至237.9 m3/s,主扇风机平均效率由优化前的52%提高至77.5%,同时减少日常通风管理人员,并降低通风管理劳动强度,提高劳动生产率,年创经济效益超过百万元,社会效益和经济效益显著。

According to the characteristics of development system and ventilation system of Hongling mine, the 3D dynamic model of ventilation system, and the methods of ventilation network optimization, machine station optimization and fan optimization selection are adopted to solve the problems of insuffi- cient of undermine total air volume, unreasonable of the middle air distribution and circulation of fresh air and dirty air in mining area. The calculation results of the Ventsim 3D ventilation dynamic simulation software show that the total air volume of the undermine ventilation system is increased from 77.7 m3/s to 237.9 m3/s, the average efficiency of main fan is increased from 52% to 77.5%. Besides that, the daily ventilation management personnel is reduced, the labor intensity of ventilation management is lowered so as to improve labor productivity, the economical benefits of ever year is more than one million RMB, therefore, the economic benefits and social benefits are significant.
