The Norwegian Tunnelling Society (NFF) is an open society for people and enterprises associated with or interested in Norwegian rock technology. A key aspect of the society’s work concerns development projects for the benefit of the industry. This takes place in close cooperation with relevant actors, and the results achieved are disseminated through NFF’s publications, handbooks and technical reports.
This publication has a relatively long history. In 1973, Kontor for Fjellsprengningsteknikk KFF published a practical handbook on rock bolting (Praktisk håndbok i fjellbolting). This became a starting point for the Norwegian Public Roads Administration’s Publication No. 72 Rock bolting from the road laboratory (Fjellbolting from veglaboratoriet), which was published in 1994, and the Norwegian Public Roads Administration’s handbook V224 Rock bolting (Fjellbolting), published in 2000 (previously handbook 215). A relatively extensive revision was carried out by the Directorate of Public Roads, before the entire process was handed over to NFF in 2017. NFF’s development committee subsequently set up a group which has ensured that it has now been updated to reflect current practice and products.
The work on the revised edition was carried out by:
Marcus Fritzøe Lawton, Bane NOR
Ragnhild Rostad, Veidekke
Thorvald Wetlesen Sr, Bever Control
Anette Wold Magnussen, Norwegian Public Roads Administration
Tone Nakstad, NFF
The drawings in the handbook were prepared by Mette Bergan, Kristine Ekseth and Arild Walberg Solerød.
NFF’s development committee was responsible for proofreading and quality assurance of the work. NFF’s International committee wanted to share this work with the international community, and is responsible for the translation.
