Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Drilling and Blasting of Rocks written by FranciscoJavier AyalaCarcedo and published by Routledge. This book was released on 2017-11-22 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Explosive Excavation Technology written by Stanley M. Johnson and published by . This book was released on 1971 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

Download or read book A Study of Selected Rock Excavations as Related to Large Nuclear Craters written by and published by . This book was released on 1967 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analogies between nuclear and conventional excavations are developed from a tabulation of data from 153 mine, quarry, roadway, and dam excavations. The following factors were used as the basis for tabulation of conventional excavation data: purpose, location, precipitation, temperature, ground water level, lithology, mass strength, structural pattern, slope plan, slope profile, depth of excavation, slope height, average inclination, and stability. It was found that average slope inclination tends to be greatest for hard material and for material lacking a well-developed structure, and that inclination tends to de- crease with increasing slope height for excavated slopes reported to be stable. The authors conclude that good analogies are to be found in shape, slope height, depth of excavation, and slope inclination. Loadings of waste material at the rim of some open pit mines may be analogous to ejecta on the lips of nuclear craters. Rubble zones found in some open pit mines may be analogous to the fallback zones of nuclear craters. Differences between preshot and postshot characteristics of cratered media must be appreciated in evaluating analogies between features of conventional excavations and preshot features of nuclear excavation sites. Brief descriptions of 21 selected excavations are presented in Appendix A. The results of this study serve as an aid to judgment of nuclear crater slope stability. Potential subjects for further study are identified.
