Abstract

En fjellbolt (10) omfattende første og andre langstrakte elementer (11, 12) vises. Det første langstrakte element omfatter en første ende (13) tilpasset for å penetrere fjell, og en andre ende (14) tilpasset for å tilveiebringe feste for aktiveringsanordninger. Det første langstrakte element er anbrakt i det minste delvis langsgående inne i det andre langstrakte element. Det andre langstrakte element kan tilpasses for tverrekspansjon langs i det minste en del av sin lengde for å forankre fjellbolten i posisjon. Et hulrom kan tildannes mellom første og andre langstrakte elementer og som strekker seg mellom første og andre ender av det første langstrakte element. Metoder for boring med fjellbolter ifølge oppfinnelsen er også beskrevet.
