矿用空气幕控制风流流动技术研究

分析了国内外矿井风流控制技术及矿用空气幕的研究进展,介绍了矿用空气幕的几种布置形式,阐述了多功能矿用空气幕在控制风流反向、控制风流循环、控制风流短路、增加或减少巷道风量等方面的作用及效果。应用结果表明,矿用空气幕安装在巷道侧壁的硐室内,不仅能有效控制矿井风流的流动,而且不影响运输巷道内的行车和行人,在地采矿山具有广阔的推广应用前景。

On the Mine-used Air Curtain for Controlling Airflow

The research progress of mine airflow control technology and mine-used air curtain at home and abroad is analyzed. Several arrangement forms of mine-used air curtain are introduced. The effects on controlling airflow reserve, airflow circulation, airflow short circuit and effects on increasing or decreasing tunnel air volume by the mine-used air curtain are expounded. The application results show that the mine-used air curtain being installed in the chamber which is on the side wall of the tunnel can effectively control mine airflow without interrupting working crane and miners. So the technology of mine-used air curtain boasts wide practical prospect for underground mines.
