Abstract

En metode for å styre boring i fjell som utføres av et fjellbor utstyrt med en trykkdrevet hammer og rotasjonsmotor. I denne metoden er borets rotasjonshastighet definert på grunnlag av verdien av styresignalel som brukes til å styre styrevcntilen som styrer strømningen av trykkfluid til rotasjonsmotoren.
