Course Description

This course will cover the new updates in the basics of drilling and blasting which are used on a daily basis in the career of blast engineering. This course will cover critical topics such as an introduction to modern blasting, how rock actually breaks from explosives, the commercial explosives and initiation systems used today, and the drilling technology available in the industry. The course is divided into short video modules with questions following each lesson to reinforce key concepts.
