Abstract: In order to solve the high dust concentrations problems on rock mechanization heading face,efficient dust removal system for rock mechanization heading face was developed.It is proved theoretically that controlled recirculating airflow ventilation and dust removal system is feasible on rock mechanical heading face of the south return air roadway with less hazardous gas,air curtain device of controlling dust was developed,the better parameter was determined,and efficient pumping dust purification equipment which can achieve closely three-dimensional dust absorption and random movement was designed.After the application of the system on rock mechanical heading face in the south return air roadway of Tangkou coal industry,the dust-laying rate of total dust and respirable dust in operation department of workface averagely reached 91.6% and 90.5%,which reduced the dust concentration in the field effectively.
