摘要
老矿山在扩能生产后,多面临通风系统不能满足井下生产需求的问题,对该类矿山通风系统进行优化改造时,往往受上部采空区、废弃井巷、已有井巷工程、矿区地质条件、现有通风状态、未来通风需求等多方面因素的限制,为此,在利用监测分析、CAD软件三维建模、通风网络解算等技术的基础上,提出了扩能老矿山生产通风系统优化改造方法。工程应用实践表明,利用该方法优化改造通风系统后,通风系统进风量增至319m3/s,满足需风量266.8m3/s的需求,且其耗电量较小,为该类矿山进行通风系统优化提供了成功范例。
The ventilation system of old mines can＇t meet the demand of underground production after capacity expansion.The optimization of this type of mines was often subject to the upper gob,abandoned roadway,underground construction,geological conditions,ventilation status,future ventilation requirements and other factors,so an optimal modification method was proposed based on monitoring and analysis,CAD software,ventilation network solver.Engineering practice showed that the inlet air of ventilation system increased to 319 m3/s after optimal modification,which met the required amount of 266.8m3/s,and the power consumption was much smaller,so as to provide guidance for ventilation optimization of the similar mines.
