常村煤矿高负压多风井复杂结构θ型通风网络分析

Complex structure of high negative pressure multi air shaft in Changcun Coal MineθAnalysis of ventilation network

对于即将投入使用的花垴村回风井,与王村风井系统形成相互影响最为密切的联合通风系统,所以优化分析分风点与汇风点的位置就成为保证通风系统稳定性最为关键的问题。针对常村煤矿花垴风井投运后形成的多风井复杂结构的θ型网络进行研究,对全矿井多风井通风动力与通风阻力匹配协同智能优化,优化分析分风点与汇风点的位置,为常村煤矿通风系统优化改造提供可靠的通风系统保障技术。最终实现常村煤矿通风系统安全可靠、经济合理运行以及便于管理的目标。

For the return air shaft of Huanao Village,which will be put into use soon,a combined ventilation system with the Wangcun air shaft system has the closest interaction,so optimizing and analyzing the location of the air distribution point and the air gathering point becomes the most critical problem to ensure the stability of the ventilation system.Aiming at the complex structure of multi air shaft formed after the operation of Huanao air shaft in Changcun Coal MineθThe research is carried out on the type of network,and the collaborative intelligent optimization of the matching of ventilation power and ventilation resistance of the whole mine multi air shaft is carried out,and the location of the air distribution point and the air gathering point is optimized and analyzed,so as to provide a reliable ventilation system guarantee technology for the optimization and transformation of the ventilation system in Changcun Coal Mine.Finally,the goal of safe,reliable,economical and reasonable operation and easy management of the ventilation system in Changcun Coal Mine will be achieved.
