The selection of appropriate blasting vibration limits for civil construction projects and quarry operations has a major influence on the overall cost, duration, and environmental impact of a project. In some cases the application of an overly conservative limit may affect the financial viability of a project to a point where it may not even commence, despite it going through all the relevant planning approvals. Low vibration limits have resulted in explosive blasting being precluded from some major projects in favour of slower, more disruptive, mechanical methods such as ripping and hammering. This has prolonged the duration of the projects and extended the community’s exposure to excavation noise and dust.

A project was initiated with Orica Mining Services to improve blasting practices and quantify the impact on the process plant. While significant improvements to blast fragmentation had previously been made, the actual benefit of those improvements to downstream processing had not been quantified and it was believed that there was scope for further improvement.

Mine Los Colorados is nowadays the main iron producer mine site of the CAP company. It is located in the Atacama region, at approximately 25 kms North-West of the city of Vallenar. The problems shown below consider the very narrow extraction (between 30 to 60m), which hampers the shovel operation (Bucyrus Erie 495 III). Due to this, it is top priority for the mine to get peak widths of extraction.
