The paper takes the deep exploitation of Sanshandao gold mine as the research subject , the methods of distribution of rock structure and lithology examination, in-situ rock stress measurement, physical and mechanical tests of rock, and fuzzy mathematic prediction are used to study rockburst tendency in deep development and exploitation of the mine, which fill the gaps for the past using only one qualitative indexes of rock to judge the possibility of rock bust, and make the evaluation results more close to the objective reality.
Reliable in situ rock stress measurement from the excavation surface
