Download or read book Crater Formed by Detonating a Row of Charges Beneath a Ridge written by Luke J. Vortman and published by . This book was released on 1968 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A row of 64-pound charges was placed 7 feet below the top of a nearly four-foot high ridge formed by the arc of a circle with its center at the row axis. The row of charges was 5 feet below the original ground surface. The volume of the resulting crater was 86 percent and 60 percent greater than craters from rows 5 feet and 7 feet deep, respectively, below level terrain. Even if one disregards the portion of the ridge above the level-terrain plane (providing an effective burial depth of 5 feet), directed blasting still provides an increase of 32 percent in volume excavated over a row buried 5 feet below level terrain. More material is ejected laterally, hence less falls back into the crater than if the ground had been level. Vertical displacement of the surface over the charges is comparable during the first 12 milliseconds, but thereafter is greater as a result of the interaction of charges in the row.

Download or read book Comparison of Craters from Rows of Charges Detonated Simultaneously and One at a Time written by Luke J. Vortman and published by . This book was released on 1967 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Row charges made up of 64-pound spherical TNT charges were detonated in one instance simultaneously and in the other instance one-at-a-time in sequence for combinations of two spacings and three burial depths. Where the charges were detonated one at a time, the crater volume was reduced to nearly 50 percent of the volume for the comparable simultaneous detonation. There was not much difference for the combinations of burial depth and spacing tested. The craters from one-at-a-time detonations averaged about 35 percent larger for the greater spacing than for the smaller spacing versus only about 10 percent difference when the charges were fired simultaneously.

Download or read book Underground Warfare 1914 1918 written by Simon Jones and published by Pen and Sword. This book was released on 2010-06-15 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simon Joness graphic history of underground warfare during the Great War uses personal reminiscences to convey the danger and suspense of this unconventional form of conflict. He describes how the underground soldiers of the opposing armies engaged in a ruthless fight for supremacy, covers the tunneling methods they employed, and shows the increasingly lethal tactics they developed during the war in which military mining reached its apotheosis. He concentrates on the struggle for ascendancy by the British tunneling companies on the Western Front.But his wide-ranging study also tells the story of the little known but fascinating subterranean battles fought in the French sectors of the Western Front and between the Austrians and the Italians in the Alps which have never been described before in English. Vivid personal testimony is combined with a lucid account of the technical challenges and ever-present perils of tunneling in order to give an all-round insight into the extraordinary experience of this underground war.

Available in PDF, EPUB and Kindle. Book excerpt: This absorbing illustrated study reveals the evolving tactics and techniques used by all sides in the underground war during 1914–18. Covering the Western Front but also the Gallipoli and Italian theatres, this study explores three aspects of World War I below ground: military mining, attack tunnels and dugouts. In 1914–17, the underground war was a product of static trench warfare, essential to survive it and part of both sides' attempts to overcome it. In 1917–18 it was rendered largely obsolete by the development of the all-arms battle as mobility was restored to the battlefield. In the stagnant, troglodyte existence of trench warfare, military mining was a hidden world of heroism and terror in which hours of suspenseful listening were spent monitoring the steady picking of unseen opponents, edging quietly towards the enemy, and judging when to fire a charge. Break-ins to enemy mine galleries resulted in hand-to-hand fighting in the darkness. The ingenuity, claustrophobia and tactical importance of the underground war are discussed and depicted in this fully illustrated study from an acknowledged expert. The artwork plates include depictions of the specialized uniforms, weapons and equipment used underground, as well as vignettes that vividly convey the many aspects of subterranean warfare during World War I.
