Who should take this course?

This course is a must for those involved with surface blasting operations including blasters, engineers, and managers. The rock blasting industry has radically changed in the past 10 years and new techniques are available to easily deal with toes, boulders, and achieving slope angles while maintaining high production. In accordance with this, new regulations are being written for vibration, not based on damage but based the human perception of vibration. With the new regulations along with the increasing demand for production modern, cost-effective blasting techniques must be employed to stay competitive.

This course should also be taken by geologists, geotechnical engineers, explosive engineers, distributors, and company executives to ensure that all levels understand how to use explosive and proper blasting techniques to achieve their desired goals.
