王庄煤矿老区通风系统调整研究

随着煤矿的不断开采，矿井规模日益增大，通风网络日益复杂，王庄矿老区处于残采阶段，西风井担负区域面临着系统调整。针对王庄矿西风井北翼封闭后通风系统存在的问题，为确保王庄矿老区通风系统各用风地点风量充足、通风系统稳定及主要通风机的合理、稳定运转，对矿井进行通风技术测定，建立矿井通风系统网络数据库，提出矿井通风系统调整方案，利用通风网络解算软件对各个方案进行了解算分析，并对各方案进行了对比分析，最后确定了矿井通风系统调整方案。这些措施对满足矿井各个时期用风需要，保证矿井安全、快速、高效生产具有重要的意义，为确保矿井通风运行安全稳定提供理论依据。

Study on adjustment of ventilation system in old area of Wangzhuang Coal Mine

With the continuous exploitation of coal mine，the mine scale is increasing and the ventilation network is increasingly complex.At present，the old area of Wangzhuang Coal Mine is at the end of mining，and the west wind well is facing the system adjustment，in view of the problems existing in the ventilation system after the closed ventilation system of the north wing of the west wind well of Wangzhuang Coal Mine，ensure that the ventilation system in the old area of Wangzhuang Coal Mine is well ventilated and stable and the main ventilator is reasonable and stable.Ventilation system technological measurement of coal mine was carried out，and the network database of mine ventilation system was established，the adjustment scheme of mine ventilation system was put forward，each scheme was analyzed by using the ventilation network solution software，and the various schemes were compared and analyzed.Finally，the adjustment scheme of mine ventilation system was determined.It is of great significance for meeting the needs of mine ventilation in various periods and ensuring the safety，rapid and efficient production of mines，to provide theoretical basis for ensuring safety and stability of mine ventilation operation.
