ABSTRACT:
In rock drilling, the dust-laden flushing air from the borehole is drawn through a coarse dust separator and a filter unit. A mixing apparatus is screwed to the bottom of the filter unit and in accordance with this invention the dust that falls from the filter unit is fed in batches to a mixing chamber of the mixing apparatus in which it is mixed with a liquid binder. The dust from the coarse dust separator is directly dumped on the ground and the fine dust from the mixing apparatus is also dumped on the ground.
