Book Description
Industrial Explosives and their Applications for Rock Excavation focuses on applications of industrial explosives in civil and mining engineering works. Explosives and their actions are explained in terms of basics, principles, and related chemistry. Explosives and initiation devices are described, including their characteristics, geometry, and timing aspects of the blast design. Designing blasts for rock excavation works is explained, including devices for obtaining large-sized blocks, construction of yards, and excavation of big foundations. Finally, criteria for the mitigation of the associated seismic disturbances are summarized. The book: provides an updated vision of industrial explosives, including the best technical advice for rock excavation; contains harmonized preliminary modules aimed at introducing basic concepts of chemistry and physics applied to the drilling and blasting technique; defines balanced mix of theory capable of providing skills to design an efficient blasting; covers excavation problems from different points of view and in different contexts; and addresses issues of drilling and loading blast-holes. Industrial Explosives and their Applications for Rock Excavation is aimed at graduate students, researchers, and professionals in mining engineering and explosives technology.

Book Description
Rock Blasting and Explosives Engineering covers the practical engineering aspects of many different kinds of rock blasting. It includes a thorough analysis of the cost of the entire process of tunneling by drilling and blasting in comparison with full-face boring. Also covered are the fundamental sciences of rock mass and material strength, the thermal decomposition, burning, shock initiation, and detonation behavior of commercial and military explosives, and systems for charging explosives into drillholes. Functional descriptions of all current detonators and initiation systems are provided. The book includes chapters on flyrock, toxic fumes, the safety of explosives, and even explosives applied in metal working as a fine art. Fundamental in its approach, the text is based on the practical industrial experience of its authors. It is supported by an abundance of tables, diagrams, and figures. This combined textbook and handbook provides students, practitioners, and researchers in mining, mechanical, building construction, geological, and petroleum engineering with a source from which to gain a thorough understanding of the constructive use of explosives.

Book Description
Three official government reports about the Plowshare peaceful nuclear explosion program are reproduced in this unique compilation: Plowshare Program Summary Report, Plowshare AEC Document, and Projects Gnome and Sedan Defense Department report.The United States Atomic Energy Commission (AEC), now the Department of Energy (DOE), established the Plowshare Program as a research and development activity to explore the technical and economic feasibility of using nuclear explosives for industrial applications. The reasoning was that the relatively inexpensive energy available from nuclear explosions could prove useful for a wide variety of peaceful purposes. The Plowshare Program began in 1958 and continued through 1975. Between December 1961 and May 1973, the United States conducted 27 Plowshare nuclear explosive tests comprising 35 individual detonations. Conceptually, industrial applications resulting from the use of nuclear explosives could be divided into two broad categories: 1) large-scale excavation and quarrying, where the energy from the explosion was used to break up and/or move rock; and 2) underground engineering, where the energy released from deeply buried nuclear explosives increased the permeability and porosity of the rock by massive breaking and fracturing. Possible excavation applications included: canals, harbors, highway and railroad cuts through mountains, open pit mining, construction of dams, and other quarry and construction-related projects. Underground nuclear explosion applications included: stimulation of natural gas production, preparation of leachable ore bodies for in situ leaching, creation of underground zones of fractured oil shale for in situ retorting, and formation of underground natural gas and petroleum storage reservoirs.On June 6, 1958, the Atomic Energy Commission publicly announced the establishment of the Plowshare Program, named for the biblical injunction to ensure peace by beating swords into plowshares. "And they shall beat their swords into plowshares, and their spears into pruning hooks; nation shall not lift up sword against nation, neither shall they learn war anymore." The Program objective was to use nuclear explosives for civilian as opposed to military purposes. The AEC San Francisco Operations Office (SAN) Special Projects Group provided the oversight management for Plowshare with support efforts from the AEC Albuquerque and Oak Ridge Offices, Sandia, the U.S. Geological Survey, and the U.S. Bureau of Mines. On October 31, 1958, the U.S. and the Soviet Union entered into a nuclear weapons testing moratorium. No nuclear tests were conducted for almost three years. During that time, Plowshare planning studies and high explosive tests would be conducted to evaluate excavation techniques. By the end of 1958, DMA had established the Peaceful Nuclear Explosives (PNE) Branch to manage the Plowshare Program. Dr. Edward Teller, then the director of the Livermore Laboratory, had outlined an ambitious Plowshare Program for fiscal years (FY) 1959-60 in his October 7, 1958, letter to Dr. H. Fiedler, AEC/SAN. The LRL-L program proposed studies in these areas: for FY 1959 - constructing a channel through the reef at Kapingamarangi in the Marshall Islands; harbors at both Cape Thompson and Katalla, Alaska; a canal across the Alaskan peninsula at Port Moller; oil extraction from tar sands and from oil shale; creating artificial aquifers; and mining by leaching; for FY 1960 - in addition to continuing the above-mentioned projects, testing a new nuclear explosive design, and using a nuclear detonation for physics experiments.

Book Description
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).

Book Description
Rock breakage with explosives has existed since the seventeenth century when black powder came into use in mining. Since then it has progressed from the invention of dynamite to the use of heavy ANFO. During the past two decades, there have been numerous technical contributions which have brought a better understanding of rock fragmentation with explosives, an improvement in drilling equipment and a noticeable evolution in the development of new explosives and blasting accessories. The Geomining Technological Institute of Spain (ITCE), aware of this progress and of the importance which the breakage process has acquired in mining and civil engineering projects, has ordered the publication of Drilling and Blasting of Rocks. The purpose of this Handbook is to give basic knowledge of the drilling systems, the types of available explosives and the accessories and the parameters that intervene in blast designing, whether controllable or not; at the same time the objectives and contents contribute to improved safety in mining. The Handbook is meant for all professionals who are involved with explosives in mining operations and civil engineering projects, as well as for students of technical schools.
