Drilling and Blasting Operations

Blasting sets the fragmentation every downstream process inherits, so a poor blast is paid for again at the crusher, in the mill and in equipment wear. This course covers designing and executing one. Delegates work through explosive types and their properties, initiation systems and timing, and blast design including burden, spacing, stemming and powder factor. Fragmentation and its measurement are treated as the actual objective. The course covers the control of flyrock, ground vibration and airblast against limits set by neighbours and regulators, alongside secondary blasting and misfire procedure, and closes on the safety, storage and legal requirements attaching to explosives.
