COURSE DESCRIPTION – Rock Blasting and Overbreak Control, Chapter 1: Explosives Engineering

Most raw materials, from which our modern society is built, are produced by the use of explosives in mines throughout the world. The construction of highways, canals and buildings are aided by the use of explosives. The plentiful food, which is available in this country, would not exist without explosives to produce the fertilizers and the metallic ores, which ultimately become tractors and other equipment.

This manual was designed to provide a systematic approach to surface blast design. The information is presented in a practical manner. The course provides the attendee with information to promote an understanding of the phenomenon and the anticipated results of the use of explosives. The formulas presented are empirical and should provide reasonable values for general job conditions. However, unusual geologic conditions can require adjustments to calculated values.


  1. Explosives Engineering
  2. Sources of Explosive’s Energy
  3. Optimizing Explosive Mixtures

This course includes a multiple-choice quiz at the end and is intended to provide 1 hour of professional development.


At the conclusion of this course, the student will have learned or been exposed to the following:

  1. Explosives Engineering
  2. Shock and Gas Energy
  3. Chemical Explosives
  4. Sources of Explosive’s Energy
  5. Identification of Problem Mixtures


Students will gain an understanding from this course of the proper approach to assessing need for and utilization of explosives for breaking rock.


This course is based on the publication, Rock Blasting and Overbreak Control, Chapter 1: Explosives Engineering. The techniques and methodologies described in this course document are applicable to most areas in the United States.


The purpose of this course is to examine the sources of explosive energy. It will also delineate the types of energy and their relationship to producing useful work in rock blasting while minimizing unwanted waste energy. Educating engineers, contractors, on these methods is key concept gained from this course.
