Book Description
The book drawing on the author’s nearly half a century of energetic materials research experience intends to systematically review the global researches on liquid explosives. The book focuses on the study of the conception, explosion mechanism, properties and preparation of liquid explosives. It provides a combination of theoretical knowledge and practical examples in a reader-friendly style. The book is likely to be interest of university researchers and graduate students in the fields of energetic materials, blasting engineering and mining.

Book Description
Excerpt from Development of Liquid Oxygen Explosives During the War The increasing cost of dynamite and permissible explosives at the time the United States entered the great war caused the Bureau of Mines to investigate all possible substitutes. The author of this paper called attention to the possibilities of liquid oxygen and carbonaceous material as an explosive compound to serve as a substitute for black blasting powder and dynamite in certain kinds of mining and quarrying work. The raw materials - oxygen and carbon - are unlimited in quantity, and production requires merely power and suitable apparatus for liquefying the oxygen of the air. This kind of explosive was first used experimentally in Germany under the name of "oxyliquit." It was tested in an early form at the Simplon Tunnel (Switzerland) about 1899, and although the claim was that the tests were favorable, it evidently was not a decided success commercially with the methods then used. Apparently one of the troubles then not realized was that the oxygen used was not pure enough, but contained too much nitrogen. In fact, the earliest experiments were with liquid air, more or less self-enriched by standing, the nitrogen evaporating faster than the oxygen. The bureau began its testing of liquid oxygen explosive in April, 1917, and experimental results, as reported in this paper were decidedly favorable, but owing to the difficulty of obtaining suitable liquid oxygen manufacturing machinery and the necessity of concentrating the bureau's explosives investigations on military explosives, further experiments had to be postponed for a while. Following the armistice, the Secretary of the Interior and the Director of the Bureau of Mines decided to send a committee of Bureau of Mines engineers and metallurgists to Europe to observe the progress in the special industries under the stimulus of war, and the author of this paper, as chief mining engineer, was asked to particularly observe the progress that had been made with liquid oxygen explosive. Mr. Rice reports that the Germans used liquid oxygen explosive extensively in nongaseous coal mines, in quarrying, and in iron mines, as well as for destructive purposes in French steel plants. At several Lorraine minette iron ore mines the Germans had installed in a permanent manner liquid oxygen explosives apparatus for mining the ore. Other European countries were not found to have used liquid oxygen explosive. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
"Oxygen was first liquefied in 1877, but the first record of its use commercially as an explosive was in 1899 when part of the famous Simplon tunnel between Italy and Switzerland was driven with this explosive. Owing to the difficulties of storing and using this liquid, little more progress was made until the Great War, when Germany, forced to experiment with any promising explosive because of her rapidly diminishing stocks of Chilean nitrates, made considerable headway in the technique of using liquid oxygen ... Since the War liquid oxygen explosives have been used extensively in France and Germany and to a lesser extent in England, Scandinavia, Italy and the U.S. It has also been, or is being, used in at least one mining property each in Mexico (Pachuca) and Chile (Chuquicamata), and was experimented with at Cerro de Pasco, Peru"--Historical, leaves 2-3.
