Chronological Development of Fragmentation Analysis Methods Over the decades, fragmentation analysis models have evolved significantly, driven by technological advancements and the growing need for more accurate and efficient methods. This article traces the chronological development of fragmentation analysis models, highlighting key milestones that have shaped the field. 1. Early Theoretical Models (1950s-1970s) The foundation of fragmentation analysis began with theoretical models aimed at predicting rock breakage based on empirical observations and basic physics. 1950s: Early models focused on understanding the mechanics of rock breakage during blasting. Researchers like L. M. Griffith introduced the concept of rock fracture mechanics, which provided a theoretical basis for predicting crack propagation in rock under stress. 1963: C.F. Konya and E.J. Walter developed the first significant mathematical model, which related explosive energy to the size distribution of blasted roc...
