矿用空气幕的研究现状及一种新型矿用空气幕

Research Status of Air Curtain for Mine and a New Type of Air Curtain for Mine

矿用空气幕最基本的作用是在煤矿井下调节风流和防治粉尘,在调节风流方面,可以起到阻断、引射、增加巷道的风流、减小巷道阻力的作用;在粉尘防治方面,能够降低煤矿井下产尘地点的粉尘浓度。在前人研究的基础上研制了一种新型矿用空气幕,有效的将掘进工作面产生的高浓度粉尘与司机隔离,并利用除尘风机将粉尘除去,达到了净化作业环境的目的,保障了作业人员的身体健康。

The role of the mine air curtain is the most basic regulation in the coal mine ventilation and dust prevention,in regulating air flow,can play a block and ejector,increase the roadway and reduce the airflow resistance effect in roadway; dust prevention,can reduce the dust concentration in coal mine dust production site. On the basis of previous studies and develops a new type of mine air curtain,the high concentration of dust is isolated from the driver heading face is generated,and the use of dust blower dust is removed,can clean working environment to protect the health of workers.
