Abstract: 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.
