Mechanised metalliferous mining occurs all over the world in many varied ground conditions. The Favona
underground gold mine in Waihi, New Zealand is no exception with underground development and stoping
occurring in ground conditions ranging from exceptionally poor to good. The poorer ground conditions
present the greatest challenges from a ground support perspective, a development advancement rate and
production perspective. This paper focuses on the challenges experienced and the solutions developed to
ensure that acceptable development rates are maintained when poor ground conditions are experienced.
