What will I learn?

This Blasting Techniques Course equips participants with hands-on skills to design and carry out safe, effective bench blasts using bulk ANFO explosives. Key areas include understanding explosive properties, calculating charge factors, determining burden and spacing, choosing hole diameter and depth, and managing non-electric initiation timing. Participants will learn to control vibration, airblast, and flyrock, utilise rock mass data for better fragmentation, and adhere to procedures for planning, communication, emergency response, and regulatory compliance in Sierra Leone mining environments.
