Abstract: According to production intensity and dust control present situation at 21007 fully mechanized working face in Chensilou Coal Mine, on the basis of the original dust removal measure, dust control technology including wet collector and wall-attachment fan drum is proposed. The swirl effect of wall-attachment fan drum can effectively reduce the dust dispersion at fully mechanized working face, and improve self-actuated wet collector to purify face dusty airflow. The field application data show that collection efficiency increases from 60.7% to over 98% according to the machine driver, the dedusting effect is significantly.
