Abstract: In order to solve the present dust removal technologies not effectively reducing the concentration of dust in the whole rock fully mechanized driving face, the efficient roadheader external spray technology, closed air curtain dust removal technology and chemical dust removal technology make up the high-efficiency compr ehensive dust-removal technology in fully mechanized driving face.The comprehensive dust technology was applied to the main haulage roadway driving face in the min ing east area of Huipodi coal mine. The results showed that using the high-efficiency comprehensive dust-removal technology could make the dust-suppression rates of total coal dust and respirable dust rate reach 96.8% and 96.4% averagely in the faces where workers work except the driving head face, which meant that the dust-rem oval effects were obvious.
