Comprehensive evaluation of deep mine rockburst proneness based on a multi-dimensional cloud model
The rockburst proneness study is of great significance for safe operation in deep mines.Taking a mine as the research subject,a combination of one-dimensional and multi-dimensional cloud models was used to construct an index system using the rock stress coefficient,rock brittleness coefficient,and rock elastic strain energy index,for eval-uating the rock burst proneness of ore rocks with 3 types of lithology in different mining levels.The results showed that within the designed mining range of the mine(levels from 50 m to-450 m),the roof dolomite exhibited an overall lesser rockburst proneness,the ore body showed a moderate rockburst proneness,and the surrounding rock of the floor exhibited an overall lesser rockburst proneness.
