Square Set System Of Timbering As Employed By The Shannon Copper Co., Ray Eugene Hoffman

Professional Degree Theses

"The properties of The Shannon Copper Co., consisting of mine and smelter, are located in the Southeastern part of Arizona in what is known as the Clifton-Morenci District. The smelter is located at Clifton and the mine at Metcalf, eight miles distant on an iron capped mountain known as Serro Preito.

From a geological standpoint the ore deposits of the Clifton-Morenci District are a freak. There are no fissure veins of any consequence in the district; all the large deposits are found in bodies, the ore usually occurring in a soft porphyry.

Underlying the iron capping on the Shannon property …

Copper Matting Blast Furnace Run, John Vivian Stevens, Frank Bowman Powell, John Dozier Shanks

Bachelors Theses

"The theory of the copper blast furnace run having been given us in the class room, we wishing to familiarize ourselves with the practical processes and the difficulties involved, selected it as the basis of an investigation of which the following is a correct report. The original ore was a high grade copper sulphide from the Ducktown, Tenn. district to which was added some heavy pyritic ore from various quarters. The latter was added to furnish the iron oxide necessary as a flux in the blast furnace and sulphur in sufficient amount to make the ore self roasting when charged …

A Special Investigation In Concrete Steel And Application To Square Set System, Horace Alonzo Hand

Bachelors Theses

"This investigation has been prompted, first, by a desire to become more familiar with concrete-steel in its general application to engineering construction, second, by the inevitable necessity of a substitute in the near future for lumber in mining construction. In first case, a thorough review has been made of principles and practice in the construction of concrete-steel structures in general, including bridges, water towers, reservoirs, viaducts, etc., as found in current engineering journals, which is the most up-to-date source of information available. Special attention has been given to best practice in reinforcing concrete to resist forces of bending, shearing, torsion …

Treatment Of Joplin Tailings, Preston King Horner

Bachelors Theses

"In the Joplin region are enormous piles of tailings, that for waste material, run very high in blende. This is due mainly to the temporary character of the mills which are built with more regard to low first cost than to receiving a high percentage of extraction. As a result we have some piles of tailings containing from 200,000 to 300,000 tons of materials that will average from about 2 to 3% zinc, and all crushed so as to pass through about #2 mesh"--Page 1.

The Lignite Coal Of North Dakota, Clyde Mckeever Laizure, James Knight Christopher

Bachelors Theses

"Owing to the great abundance of coal, both anthracite and bituminous, in the United States, no state need suffer for the lack of it, but to those states like North Dakota, situated in the great plains region and at great distances from such coal supplies, the price of these coals makes them almost luxuries. In the last few years however, the development of the lignite coal within the state of North Dakota has shown an abundance of fuel for many years to come, which, though at one time considered "A poor excuse for poor wood," now competes successfully with any …
