Field experiment was performed mainly to test weather or not the blast burden gives significant influence on vibration level. Parallel with the main idea, investigation was extended to measure size distribution of fragmented rocks. The relationship between peak particle velocity (PPV) and scaled distance reveal three relationships for three different scenario of burden, which indicate that the blast burden influences vibration level. Fragmentation measurements of a muckpile using digital image give plausible results. Using software known as Split Engineering, the fragmented rocks resulted from three scenario of blast burden were calculated and presented in size distribution curve.
