The development of an approach to define the rockburst-prone areas in mines is discussed. The role of bursting indices, in-situ approaches, geological features, mining conditions and observations in identifying the burst-prone mine workings is outlined. In addition, a laboratory investigation was conducted on rock specimens from Sudbury Nickel Belt in Canada to determine the important indices and rock properties. It has been observed that the decrease modulus index depends on the burst-proneness index, strength, brittleness and the strain energy stored in the rock specimens. The burst-proneness index exhibited reasonable correlation with the Schmidt rebound hardness number and shear wave velocity. The use of the decrease modulus index and burst-proneness index to assess the burst-tendency of hard rocks is also described.
