An Investigation Of The Mechanics Of Oil Migration From The Source Beds To The Reservoir Beds, William Reed Quilliam

Professional Degree Theses

"The study of the migration and accumulation of petroleum has very naturally been analytic, with the result that we have had a variety of studies of its several features. the generation of petroleum, its migration and its accumulation in reservoir rocks is not a rapid process which may be accomplished and terminated in a comparatively short time, but one of long and almost continuous operation from the time of its inception. In this study the author is not attempting to formulate a new theory for the movement of oil from its point of origin to its final point of accumulation …

Internal Combustion Engines, Neal Ham

The Manufacture Of Liquid Oxygen And Its Use As An Explosive, Francis Kinlock Middleton Hunter

Professional Degree Theses

"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 …

The Role Of Geology In Prospecting For Lead And Zinc In The Tri-State District, William Ferdinand Netzeband

Professional Degree Theses

"The present generation has seen many changes in all phases of human endeavor, and the changes which have been made in the extraction of metals from the earth are not the least or these. The application of science to our industries has revolutionized many of them. Today quantity production in our factories is an accepted thing, and in the mines, application of the same principles has made possible the working of the low-grade copper deposits of Utah, Arizona, Chile and Belgian Congo. The mining industry has made use of almost all of the sciences in one form or another to …

Concentration Of Oxidized Lead Ores, Stephen Michael Burke Jr.

Professional Degree Theses

"In the pages of this paper an attempt is made to describe present methods of concentration and flotation of the oxidized ores of lead. The method employed is the presentation of the actual o operation of several mills which have been treating such ores during 1926 and 1927.

The plants described are representative operations and form some criteria for the performance of such ores under different conditions. In addition to those concentrators which are described, there are perhaps several small installations which are recovering lead from old mine dumps and tailings piles. It is difficult and almost impossible to obtain …

Fluorspar Mining And Milling In Southern Illinois, Henry William Hurst

Professional Degree Theses

"Fluorspar is fully as necessary a material in certain phases of steel manufacturing as the metal that enters the furnace. Without it, the basic open hearth practice probably would not have reached its dominant position among steel-making methods. Of the entire output of fluorspar, 80 to 85 percent is used in basic open-hearth and electric furnaces as a flux and detergent and there is today no known substitute.

The mining of the ore on a large scale requires extensive underground workings, much the same as is found in metal mines. Since high extraction can not be accomplished the milling of …

The Economics Of Engineering Testing, Gerald Franklin Rackett

Professional Degree Theses

"...It becomes the province of the engineer in his functions of designing and building the various units so prominent in our contemporary civilization, to guild with due regard for economic and mortal safety. To do these things he must have reliable data of the behavior and characteristics of those materials with which he works. The data can only be obtained by the systematic testing of engineering materials and the articulated units and fabricated structures that are built with them"--Safety, page 7-8.

Mining Methods At The Higueras District, State Of Coahuila, Mexico, Harry Herbert Hughes

Professional Degree Theses

"The Higueras district, in the State of Coahuila, Mexico, is little known even in Mexico; and it is probably safe to say that not one out of every hundred engineers in the United States has even heart of it. This is easily accounted for by the fact that the district is small and relatively unimportant economically. Also, as one becomes more accustomed to think of mines, such as some of the big copper deposits, with productions running into thousands of tons daily, there is a tendency to pass over the small ones, giving them only a passing thought, if that. …

Rill Stoping In The Butte District, Butte, Montana, Albert Booth Needham

Professional Degree Theses

"Numerous methods of stoping have been used in the mines of the Butte District, Butte, Montana, depending on the shape of the ore bodies, conditions of the walls and presence of fault zones or heavy ground. One of the methods tried out successfully in the past few years is that of using rill stopes, both open and timbered. The ideal conditions for adopting this method of mining require veins with nearly vertical dip so that the ore will slide into the chute. The author attempts to describe the various steps including how the development is done, how the stopes are …

The Fissure System Of El Potosi Mine Of El Potosi Mining Company, Santa Eulalia, Chihuahua, Mexico, Carl E. Millikan

Professional Degree Theses

"The fissures traversing the country were the means of mineralizing the district. The North-South system of fissures have been determined to be pre-mineral, hence the most important. Their intersections with cross fissures are the regions of orebodies, and the intersections have always produced ore of mineable quantity. Especially important are the intersections of fissures in the "favorable" (fossiliferous) limestone beds. The favorable limestones are easily recognizable and can be traced thru all parts of the district because of their distinctiveness and the uniformity of the structure of the region"--Summary, page 19.

Engineering Practice In The Tri-State District, Richard John Stroup

Professional Degree Theses

"Mining operations of the zinc and lead deposits of Southwest Missouri, Southeast Kansas and Northeast Oklahoma forming what is known as the Tri-State District are peculiar in many ways. The 'old country' with its shallow gougings and more or less crude methods has practically passed; methods have been improved with the increased size of operations, and the Engineering Department has grown into an indispensable link in the mining operations of practically all the operating companies. But traditions often die hard. Many phases of mining operations are peculiar to this District alone, and likewise engineering practice has its peculiarities"--page 1.

Accident Prevention In Cement Plants, Edward Rees Abbott

Bachelors Theses

"The cement industry as a whole took up accident prevention work along with the pioneers. With the organization of the Portland Cement Association, a Bureau of Accident Prevention was formed. This Accident Prevention Bureau, by sending out literature, holding competitions, collecting and tabulating results of accidents collected from every cement manufacturer and affiliating with National Safety Council as the Cement Section, has made rapid strides each year, until today it is doubtful if any other branch of manufacturers can show more improvement in accident records than the cement industry. In spite of their marked improvements each year, there were 47 …

Economic Geology Of Northern Angola, Artileus Vosteen Eulich

Professional Degree Theses

"Most of the mineral deposits have been known to exist for over a generation but efforts to mine them usually met with failure. The most signal discovery, that of diamonds, was made only in recent years. They are the only substance coming under the category of mineral which are being exploited on a large scale. Energetic efforts are being made to find petroleum in commercial quantities. There are still vast areas practically unexplored which if thoroughly prospected might lead to more discoveries. It is difficulty, however, for one who has prospected for two years in Angola without any particular success …
