| Abstract: | In view of the fact that the existing continuous coal mining machine dust removal system can not solve the problem of dust overrun during the operation of the driving face of Shendong Daliuta Coal Mine,we point out the design defects of the existing continuous coal mining machine de-dusting system,such as the difficulty in atomizing the external spray,the small dusting air volume and the unreasonable layout of the suction outlet,and propose improvement schemes and design a set of continuous coal mining dust removal system suitable for the excavation face of Shendong Daliuta Coal Mine.The concentration of total dust and respirable dust at the working point of the coal machine driver at the heading face increased by 83.19%and67.23%respectively compared with that before the improvement. |
