The mining industry, a critical component of mining cost is Explosive cost. This research paper aims to explore the relationships between key blast design parameters—such as explosive density, powder factor, stab holes, and overall blast design—and their effects on blast fragmentation in open-pit mining by designing different blast design in LS DYNA and SHOTPlus. The goal is to develop a more efficient blasting process that not only improves material fragmentation, thus enhancing loading and hauling efficiencies. Blast design is carried out before every blast and simulation is done to predict the fragmentation. Use of stab hole with production hole is done in different cases to improve the powder factor. Rock fracture and the ensuing fragment muck-piling are simulated using a hybrid finite-discrete element approach (FEM-DEM) under a variety of blasting conditions. To calibrate the hybrid FEM-DEM technique, the modeled cracked, crushed, and long radial fracture zones are compared to the body of existing literature. Furthermore, the hybrid model accurately simulates the process of rock fragmentation that occurs during blasting. The findings show that the hybrid FEM-DEM approach performs better at precisely simulating the dynamic fracture behavior of rock under blast impact loads than either solely continuous or discontinuous approaches.
