In this two-volume text and reference, Hustrulid (Colorado School of Mines) presents articles describing the principles involved in hard rock blasting as applied to surface excavations in general and open pit mines in particular. Volume I (General Design Concepts) introduces the basic engineering concepts and building blocks that make up a blast design. Volume II (Theoretical Foundations) provides additional depth and breadth for better understanding of some of the fundamental concepts so that engineers can improve not only their blast operations, but also their ability to understand the content and potential application of blasting papers appearing in the technical literature. Annotation c. Book News, Inc., Portland, OR (booknews.com)

Divided into two volumes, this accessible work describes the principles involved in hard rock blasting as applied to open pit mines. A large number of examples illustrate the application of the principles. The first volume introduces basic engineering concepts and the building blocks that make up a blast design. The second volume goes into more depth to provide a better understanding of the fundamental concepts involved in rock blasting. Both volumes provide a basis for engineers to improve their blasting operations and their understanding of blasting papers that appear in technical literature.
