Opencut Blasting / Quarrying

Example of Opencut blasting - 00:08 sec (650kb)

Opencut mining (Coal and Metals) and Quarrying utilise Blasting at the early stages of the mine production processes.
Blasting issues relate to:

• Achieving production targets
• Cost effectiveness
• Environmental controls (Flyrock, vibrations, Airblast, fumes)
• Designing blasts for unusual or irregular rock faces
• Achieving desired fragmentation outcomes suited to mine equipment and end-product specifications
• Technick has worked in these areas for nearly 40 years in Australia and Asia.
