梁北煤矿通风系统稳定性分析

Stability analysis for Ventilation System of Liangbei Coal Mine

本文根据梁北煤矿的实际情况,进行通风阻力测定,得出系统的风量及风阻值;利用矿井通风网络分析软件VNT对梁北煤矿的通风系统进行分析解算。通过改变中央风井风机、东风井风机的叶片安装角度,分析相互之间的影响,然后采取保障通风系统稳定性的相应措施。通过矿井通风系统稳定性分析能够有效保证矿井的安全生产。

According to the actual situation of Liang Bei coal mine, the ventilation resistance is measured and system air volume and wind re-sistance are obtained. Firstly Liang Bei coal mine ventilation system is resolved and analyzed with the ventilation network analysis software （VNT）. According to changing the blade setting angles of the central ventilating well fan and the Eastern ventilating well fan, we analysis the stability influence on the both. Then taking corresponding measures to guarantee stability of ventilation system. So it is efficient to guarantee the mine safety production by analyzing the stability of mine ventilation system.
