Abstract: In regard to the increased coaldust and the characteristric of its apt explosion in Fengfeng group’existing mines;the group has conducted a series of integrated dustproof experiments by the improving of the Sheraser'spraying devices,making the water curtain on the tranfer point of the mining face.and adopting electromagnetic and coal integration control on the face conveyor. Meanwhile, the dustproof and removal experiment have been conducted with different water infusion methods according to different seams and the media identifies. Thus dust removal rate is up to more than 90%,and a safe working environment for the mining face is created
