Summary
Vertical and near vertical joints can have an important effect on tunnelling operations in rock. This paper describes an inclined drilling programme to study jointing along nearly 5 km of tunnel within the Kielder Water Scheme. Drilling problems are discussed, logging methods are described and the results are given. It is concluded that inclined drilling can have an important role in tunnel site investigations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
