摘要：During the tunnel construction process,a large amount of dust is generated in tunnel construction,blasting,tunnel dumping,shotcrete,on-site steel welding,waterproof layer welding,concrete construction and other construction processes.In this paper,dust particle type,dispersion,particle size and other characteristic parameters are defined,certain preliminary test conditions are set to simulate the process of dust injection,and certain research results are obtained.Apart from this,a new dustproof concept for anchoring and shotcreting construction is proposed,and a new type of mine wet dust collector was designed.The dust-containing airflow generated by the anchor spray is absorbed into the dust remover through the dust hood,and is discharged after being concentrated and purified by the dust remover.At the same time,the dust remover mechanism is simple,the operation is convenient,the water consumption is small,and the utility model has important practical value.
