Abstract

The highconcentration dust control technologies in the tunnel construction by mining method are summarized systematically by literature investigation. Firstly, six hazards of dust are introduced, and the mechanism of dust production in four main processes of drilling, blasting, mucking and shotcreting is described. Secondly, the dust control technologies of mined tunnel are sorted out according to five categories of reduction, lowering, exhaust, remove and stop, and the dust control mechanisms of these technologies are introduced. Finally, the prospects of the dust control technology in pertinence, equipment, materials and new methods are analyzed.

Key words： highconcentration dust; tunnel construction by mining method; dust production mechanism; dust control technology
