ABSTRACT:
A sectional scraper device which is foldable in zig-zag position by remote pulling means and which can be let down through a clad bore hole and can be deviated to follow layers of mineral to be mined by a to and fro movement of the scraper device combined with transport of loosened minerals by liquid circulation through the bore hole. The scraping action may be strengthened by the action of liquid jets emanating from the scraper device.
