提高矿井主扇通风经济效益的途径和措施

Approaches and Measures for Improving the Economic Benefits of Main Fan Ventilation at Coal Mine

从分析影响矿井主扇耗电量入手 ,结合我国煤矿井下通风中存在的一些问题 ,以轴流式通风机组成的通风系统为例 ,从通风网路。

The factors influencing the electric power consumption of main fan at coal mine was analyses. As an example, a ventilation system formed by an axil-flow fan has been considered. Based on some problems existing in mine ventilation of main fans, approaches and measures for improving their economic benifits have been discussed from the three respects of ventilation networks, main fan and their performance matching.
