Rill Stoping In The Butte District, Butte, Montana, Albert Booth Needham Jan 1925

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.

Masters Theses

"The ultimate object of this refractories investigation is to develop a body for zinc retorts, or changes in the method of their manufacture, that will result in better retorts than the ones now in use. In doing this, the question of permissible cost must, at all times, be kept in mind. The immediate object of the present phase of this investigation, of which this thesis covers only a part, is to determine the physical and chemical properties of the refractories (fire clays, grogs, bodies, etc.) now used for the manufacture of zinc retorts. This will be a basis for later …

Engineering Practice In The Tri-State District, Richard John Stroup Jan 1924

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.

Economic Geology Of Northern Angola, Artileus Vosteen Eulich Jan 1924

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 …
