Abstract:
A reliable rock fragmentation prediction model is an essential aspect of the blasting operation for improved production. Blasting affect all the downstream operations, including loading, hauling, and processing, there is a need for blasts to be designed in conjunction with fragment sizes modelling : Research methodology; The data gathered was used to predict blast fragmentation using the selected models. This was to determine pre-blast particle size distribution at the sites. After collecting the bench data, a blast was done and images of the fragments taken for analysis using Split-Desktop. The process was repeated for six blasts considered for each quarry. Data collection process. The blast fragment size prediction data was collected prior to blasting through field measurements while the blast size measurement was done by taking images of blasted rock materials
