云岗煤矿大功率风机供风巷道漏风研究

Study on the roadway leakage using high power fan to ventilate in Yungang Mine

瓦斯矿井掘进工作面普遍采用抽出或压入式风机供风来稀释工作面掘进期间产生的瓦斯,在日常生产过程中由于风筒漏风以及风筒破损等原因,极易导致工作面供风不足导致瓦斯超限。在日常生产过程中通过不断的实践摸索,使用风筒箍和铁质风机三通,使漏风问题得到了很好地解决。

The gas mine heading face generally use drawn or pressed type blower air supply to dilute the gas generated during the working face advancing, in the daily production process due to air leakage and air duct damage, can easily lead to insufficient air supply of working face gas gauge. In the daily production process through the exploration practice, using a hairdryer andiron hoops fan three, the leakage problem was solved.
