Dislocation Method Study on Rock Damage Induced by Underground Mines Blasting

Abstract:

To develop an appropriate rock damage criterion, a proper description of structure of the rock mass, indicating potential key rock blocks, its mechanical properties as well as the type and characteristics of the explosive used and the blasting mechanism, drill hole pattern, use of delayed detonation and sequence of blasting are required. In this paper the intended damage criterion has to be based on the mechanical response of the rock to cyclic loading which is related to the size of the blast and type of explosive used.
