基于VSE的大南湖一矿通风系统现状仿真与评估

Simulation and Evaluation of Ventilation System in Dananhu No.1 Coal Mine Based on VSE

为了掌握大南湖一矿通风系统现状,科学评估其安全性、稳定可靠性及合理性,对全矿进行了通风参数精准普查,基于VSE软件对通风系统运行状况进行了仿真与评估。结果表明大南湖一矿通风系统存在部分巷道微风、回风大巷风速偏高、井下通风设施较多、部分角联分支易发生风流转向、矿井通风阻力分布不合理等问题,为系统的优化改造指明了方向。

An accurate survey of ventilation parameters was carried out in Dananhu in order to grasp the present situation of ventilation system in Dananhu No.1 Mine and scientifically evaluate its safety,stability,reliability and rationality.Based on the VSE software,the operation of ventilation system was simulated and evaluated.The results show that there are some problems in ventilation system of Dananhu No.1 Mine,such as breeze in some roadway,high wind speed in return air roadway,more ventilation facilities in underground,wind flow steering in some angular branches,unreasonable distribution of ventilation resistance in mine,etc.It points out the direction for the optimization of the system.
