Research and Application of Mining Foam Dust Removal Technology in Fully Mechanized Excavation Face
Aiming at the problems of high dust intensity,high wind speed and easy dust accumulation of 3306 fully mechanized excavation face in Wangpo Coal Mine,easy blockage and damage of high pressure spray dust removal equipment inside and outside the roadheader body,high dust oiliness and difficult adhesion of fog drops,etc.,which lead to excessive dust and serious pollution in the working area,the research on mining foam dust removal technology applicable to the fully mechanized excavation face in Wangpo Coal Mine was carried out.Finally,industrial demonstration was carried out at 3306 fully mechanized excavation face of Wangpo Coal Mine.The application results show that,in the position behind the roadheader with the highest dust mass concentration,the dust removal rate of total dust can reach 74.96%,and the dust removal rate of exhaled dust can reach 71.50%.The dust removal effect is good,and the environmental quality and visibility of the whole roadway have been significantly improved.
