The orebodies dip moderately (45°) and mining is currently about 1,800 m below Mount Black. As might be expected, ground conditions are challenging regarding rock stresses versus the strength of the rock mass. Over 22 years, from 1983 to 2015, in situ rock stress measurements have been made at 16 sites at varying depths from about 500 to 1,800 m below surface. This data is documented and summarised, with depth and possible geologic and structural controls, to provide an understanding of what locally controls Rosebery’s rock stresses. This understanding has been used to better appreciate some aspects of the mine’s challenging ground conditions.
