Excessive Dust produced by<br />
cutting action of<br />
Roadheader<br />
Can be reduced by using<br />
increased ventilation<br />
Use of high pressure water<br />
for dust suppression may<br />
not be effective or produce<br />
more problems with the<br />
formation to be cut and the<br />
safe, efficient operation of<br />
