Abstract

A method for drilling venting ducts in underground workings, e.g. coal mines, has the top of the venting pipe (1) fitted with a connecting pipe (3) topped by a flange (4) onto which the drilling adaptor is clamped. The adaptor (5) has a top flange (6) with a seal clamped between two flanges, to take the boring bit. The seal comprises a flexible plate with a central hole and radial slits to enable the tip of the boring tool to be inserted. The adaptor is fitted with an upwards sloping gas extract duct (13) and a lateral duct (14) for extracting the debris and water mixture.
