... and procedures have been well established (e.g. Goodman 1989, Hudson 1993, Hudson & Harrison 1997). For any practical rock mechanics or rock engineering the key issue is the generation of adequate and accurate input data which we need in analyses and design techniques. Over the last 15 years, several...
