The Underground Operators’ Conference has been gathering strength ever since the first conference was held in 1977. The 2005 conference was once again an outstanding opportunity for owner and contract miners and their associated suppliers, consultants and researchers to engage in a common forum to discuss a number of operating issues that have confronted and been solved by the underground mining community. The papers delivered and co-authored by owner and contract miners from across Australia was leavened by a sprinkling of overseas papers. It is fairly obvious that regardless of country, education standard of personnel or sophistication of mining methods, the issues confronting mines are much the same. Their solutions, at times, are quite novel and it is hoped that others will learn from fellow operators in other countries. Content: Front Matter • Table of Contents •Section 1. Keynote Addresses 1.
