Abstract: Dustproof technology for rock gangway fully mechanized working face is the main problem troubled the drifting for a long time and it is the emphasis and difficulty in coal occupational hazards prevention and control work. According to the characteristics of dust distribution and internal and external spraying of road-header, dust extraction by negative pressure, closed dust suppression by air curtain, dust extraction by water curtain and other characteristics of comprehensive dustproof technology, we have taken some effective measures in the process of rock gangway fully mechanized mining in this paper which reduced the dust concentration and effectively improved the working environment.
