Abstract

1438367 Boring earth &c COMPAGNlE FRANCAISE DES PETROLES and SOC GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES ALSTHOM 22 Aug 1973 [23 Aug 1972] 39862/73 Heading E1F Drilling apparatus comprises a chamber 1 within the drill 2, Fig. 1. Liquid being supplied to the chamber at high velocity e.g. 150 m/sec via channels 10 orifices 9 and 12 and material within the chamber is comminuted autogenously. The ground material leaves via sieve apertures 14. In use the core material 5 is pre broken by being forced at an angle into the chamber 1 by a ramp 8. The spoil channels 6 around the drill may be flushed by liquid. In Fig. 3 flushing is effected by the slurry itself passing out via tool flushing grooves 13.
