Abstract
Blast-induced rock fragmentation affects the productivity and efficiency of downstream mining operations, including haulage, crushing, grinding, and excavation. Rock fragmentation needs to be monitored regularly to improve blast design. The study aimed to improve blasting efficiency by utilising WipFrag software analysis for fragmentation analysis following blasting. This effort aims to use image analysis to study rock fragmentation in the quarry at Hume Cement Gopeng Plant, Perak. WipFrag software is used for image analysis in fragmentation investigations. The images were taken from six different blast event. The investigation also contrasts the outcomes of a picture with a lower resolution and a more excellent resolution. In addition, the effectiveness of the analysis was evaluated by comparing the elevation of the images taken. Findings indicated that most blasts fragmented rock to a useful size, eliminating the need for additional blasting. Higher resolution images showed an increased proportion of analyzable particles, while images captured from greater heights provided a clearer view of rock distribution on the upper portion of the pile. Thus, this study demonstrates the effectiveness of WipFrag image analysis in optimizing blast design, ultimately enhancing productivity and reducing costs in mining operations
