Speakers and Topics
Geology Level One+
Kurt Oakes, ISEE Board of Directors (bio)
Geology is one of the dominant factors affecting overall blast performance. This presentation will provide an illustrative view of geology and the associated various rock structures and physical characteristics that affect blast results. Blasters, drillers, and explosive engineers should understand rock characterization and their potential influence on blast results. Rock type and the structural formation of the rock mass to be blasted influence blast performance in many different ways. Various rock types exhibit unique inherent strengths and weaknesses based upon their composition. Structural variations and imperfections alter the geologic characteristics from their original depositional condition. Geologic structures and unconformities create barriers that affect and limit the ability of the explosive energy to fragment the rock mass. The blaster needs to have or develop the ability to “read the rock”, and identify characteristics that affect and influence the blast outcome. This presentation is not intended to be a geology text, but rather a discussion of geologic factors which can affect blast results. Terms used are recognized throughout the industry. The content of this presentation is based upon published text in the “18th Edition of the ISEE Blaster’s Handbook”.

Flyrock is a blaster's worst nightmare. Planning for it is your best defense.
Bulk Explosives Equipment and Use
Mark Curry, Orica (bio)
An overview of the different form-functions of bulk equipment and trucks and their intended purpose and some “creative” uses of this equipment to load holes.
Blasting Safety Level One+
Maggie Hettinger, BME (bio)
The International Society of Explosives Engineers, Blasting Fundamentals Level 1+ Blasting Safety presentation provides a broad overview of various safety topics of importance to those in the blasting industry. Safety should be everyone’s first priority and the goal of this presentation is to reinforce that idea while touching on key blasting specific issues. The topics covered include how to plan a comprehensive safety program, the selection of qualified personnel, personal protective equipment, general hazards, blast site safety management, initiation system best practices, standard blast procedures, and the post-blast inspection process.
