A questionnaire related to mining at great depth and in very high stress conditions has been completed with the assistance of mine rock mechanics personnel on over twenty mines in all mining districts, and covering all deep level mines. The objective of the questionnaire was to identify and where possible, quantify problems associated with deep level and high stress mining taking place at present as well as anticipated changes in the future.
