本文介绍了一种防止风流短路的新措施——风门闭锁。该闭锁装置克服了以往由于两道风门同时敞开造成井下风流短路的现象。对稳定矿井通风系统,提高矿井有效风量,保证通风安全具有重要作用。
This article describes a new measure to prevent the wind short circuit - the damper. The locking device overcomes the phenomenon of short-circuit airflow caused by the simultaneous opening of two air-doors in the past. It plays an important role in stabilizing mine ventilation system, increasing effective air volume in mine and ensuring ventilation safety.
