摘要
通风系统是矿井生产的重要保障.为了保证矿井的生产能力与安全性,介绍了矿井的主要概况,并对通风系统进行了分析;对采掘交替工作面的风阻进行测定,并提出了 4 点问题和 3 种方法;建立通风系统优化仿真模型,通过分析得到 3点优化结论;研究了自然风对通风系统的影响,确定两台通风机之间相互作用较小,不影响系统优化后运行的稳定性.
Abstract
Ventilation system is an important guarantee for mine production.In order to ensure the production capacity and safety of mine,the main general situation of mine was introduced,and the ventilation system was analyzed;the wind resistance of mining and excavation alternating working face was measured,and four problems and three methods were put forward;the simulation model of ventilation system optimization was established,and three optimization conclusions were obtained through analysis;the influence of natural wind on the ventilation system was studied,and it was determined that the interaction between the two fans was small and did not affect the stability of the system after optimization.
