| This project shows a methodology for developing a 3D model of the cracks generated in small scale blasting tests. To obtain the 3D model, the blasted specimen is cut into several slices. Then dye-penetrant is applied to the cut surfaces to intensify the crack trace patterns. These trace patterns are then used to create digital 3D models in AutoCAD. By a visualization of the internal crack network it becomes possible to describe how and where the cracks are created. Crack families can be identified based on angles, lengths and origin and characteristics in terms of crack density and intersection densities e.g. can be determined. The proposed crack quantification method and the results obtained with it will be combined with the fragmentation and surface roughness results in other projects where model scale blasting was used to verify how crack development from previous blast influences rock fragmentation in subsequent blasts. In addition, the crack influence in the surrounding rock by using different blasting conditions. | |
