The report is the first comprehensive textbook on a relatively new method of construction originating from research into the large-scale use of explosives for construction purposes. The central idea is that explosives can be made to do more work for the civil engineer than just break up rock: various types of excavations and explosion-generated effects can be designed and produced safely, quickly, and in many cases cheaper than by the use of other techniques. The overall concept, design approach and procedures, and the operational consequences of using currently available techniques are fully described. Emphasis is on the adaptability of the method, and its present and future potential as a cost competitive tool in various construction roles. The report deals with the mechanism of crater formation and characteristics of explosion-produced craters. It covers the types of projects where such craters have useful application; how to choose the proper explosive; how to design the charge emplacement and firing system; and how to evaluate the potential hazardous effects from detonation. The field operations associated with using the method are described and the postshot engineering considerations are discussed. An example is given illustrating how to analyze a typical excavation project. (Author).
