Abstract (en)

[origin: WO2013120475A2] The invention relates to a device for dry drilling using drilling debris flushing and dust extraction, which is suitable for use in a drilling rig having one or especially also a plurality of drilling trucks, wherein each drilling truck having a dust extraction means and drilling debris collector (2') is assigned a vacuum generator (3) that is stable with regard to volume flow, especially in the form of rotary piston blowers (10, 11, 12), and a surface filter (4, 4', 4") having compact elements (5, 6) and serving as a dust filter (2) and drilling debris collector (2'). The surface filter (4) is designed in such a manner that said filter reliably separates both the drilling debris and the dust.
