煤矿井下控风方法创新实践

Innovation and practice of mine underground airflow control method

矿井通风系统是煤矿井下正常生产的重要组成部分。通风系统根据生产接续变化而变化时,需要通过增阻或减阻等方法来调节不同地点的风速风量,进而使系统合理达标。大柳塔煤矿的测风员在多年的调风实践过程中总结出了许多实用而简便的调风控风方法,使得井下的风量调配更加迅速准确,通过总结这些控风方法将帮助更多矿井有效控风。

Mine ventilation system is an important part of the normal production in coal mine. According to the change of mine production,the ventilation system needs to be adjusted,that is,by resistance increasing / reducing method to regulate the wind speed and air volume at different locations. In Daliuta Coal Mine,the wind measurement member summarized many practical and simple airflow control methods after years of practice,which make the airflow adjusting more quickly and accurately. The methods are of referential significance to other mine airflow control.
