| Abstract: | In order to solve the dust problem in the excavation face of track roadway in a mining area,the enclosed dust removal system with wall air duct was applied.The test results show that the closed dust removal system can realize synchronous propulsion with the roadheader,which has the characteristics of small size,easy operation,long life,low cost and small energy consumption.After the application,the total dust concentration at the driving point of the roadheader decreased by 98.7%and the respirable dust concentration decreased by 98.2%. |
