Drilling, Explosives and Blast Design for Mining Operations

Drilling and blasting are critical activities in mining operations because they directly influence fragmentation, loading efficiency, haulage performance, equipment productivity, vibration exposure, cost control, and workplace safety. A successful blast design must balance geological conditions, rock strength, jointing, drilling quality, explosive selection, blast geometry, timing logic, exclusion controls, and operational objectives. This program provides a structured applied learning pathway for mining engineers, geologists, drilling supervisors, blast engineers, quarry managers, and technical field staff. Participants will learn how drilling accuracy, hole layout, burden, spacing, stemming, sub-drilling, and sequencing influence blast outcomes and downstream mining productivity. The course explains explosive properties and their implications for controlled blast planning, while maintaining strong emphasis on safe handling, regulatory discipline, documentation, and field control. Participants will examine charge planning logic, powder factor interpretation, and professional methods for adapting blast assumptions to rock-mass conditions. The program also explores fragmentation mechanisms, muckpile characteristics, oversize control, vibration awareness, and post-blast checks. Safety modules address blast permits, exclusion zones, misfire management awareness, communication protocols, and continuous improvement through documented performance review. It is ideal for technical professionals seeking to strengthen blasting performance while maintaining safe, controlled, and compliant mining operations.

Participants will achieve the following objectives by this course:
