<p>The invention relates to a method and arrangement for reducing dust-related problems in rock drilling. Air and liquid mist is supplied into a drilling hole to moisten the dust that comes off the drilling hole. The air and moistened dust exiting from the drilling hole are led to a dust separator, dust portions that collect into the dust separator being removed therefrom at suitable intervals. When dust is to be removed from the dust separator s filter, liquid is supplied to the portion below the filter in a mist-like form or as small droplets in connection with the dust removal to moisten the dust which then falls out of the lower end of the dust separator.</p> |
