Abstract

Framgangsmåte for boring av borehull i grunnen, ved elektrisk utladning generert ved hjelp av høyspente pulser mellom elektroder. Minst ett av · følgende elementer anvendes: a) elektroder som er bevegelige innbyrdes og i forhold til boreskjærets kjerne på en slik måte at bunnhullet sikres fysisk kontakt for alle elektrodene mot bunnen , b) dysestråling av den sirkulerende væska, med anslagspunkt mot hullbunnen og strålevektorretning som er spesifikk i forhold til de aktuelle utladningsgapene, slik at den løfter og fjerner primærfragmentene øyeblikkelig når de løsner, c) plassering i borehullet av minst en høyspent pulsgenerator og med strømtilførsel fra overflata, d) dekning av borehullets tverrsnitt ved en kombinasjon av roterende eller oscillerende bevegelse av boreskjærets kjerne og et flertall elektroder plassert på skjærflata langs én eller et fåtall radier og tangenter, e) ringformet hull-laging med kjernelagring, kjernetransport, sirkulasjon i borehullet i lukket sløyfe av utladningsvæske med enregitilførsel for å drive dette, utladningsvæskerensing og lagring av fragmentene. Det er også beskrevet en boreanordning for gjennomføring av denne framgangsmåten.
