Research and application of affusion dust removal technology in the mechanized excavation faces

For comprehensive tunneling working face in coal roadway,the production process produce large amounts of coal dust. In the mining working face where the coal bed get into the zone of fault and fold development,and the coal seam with large dip angle and thickness,the dust amount is commonly big,which has seriously affected the safe and efficient production of coal mine. In order to ensure staff's health,make the dust concentration in the workplaces to achieve the requirements of the state,and implement safety production,taking the comprehensive tunneling working face in coal roadway as the object of experimental research,the coal seam affusion dust removal technology was discussed in this paper,the injection technology was described in detail,and the parameter change of the dust concentration before and after water injection was compared,which provides guidance for the future affusion dust removal in coal seam.
