Modern Hydraulic Filling In Underground Metal Mines, Rainer Gevers May 1956

Modern Hydraulic Filling In Underground Metal Mines, Rainer Gevers

Bachelors Theses and Reports, 1928 - 1970

While the practice of back-filling is almost as old as mining, it was only when modern machines made possible the removal of vast tonnages of rock, that the support of underground workings-- by filling work-out stopes-- became peremptory from both the humane and economic aspects.

Shaft-Sinking Investigation, Johan De Beer May 1956

Shaft-Sinking Investigation, Johan De Beer

Bachelors Theses and Reports, 1928 - 1970

During the past few years there has been a tremendous advance in the rate of sinking shafts. The sinking of shafts has always been one of the more costly and time consuming operations in the development of a mine. Shaft sinking is a long-term operation and only in the past few years has there been a remarkable increase in the rate of sinking.

Mine Cars Of The United States, Edward Sadar Apr 1956

Mine Cars Of The United States, Edward Sadar

Bachelors Theses and Reports, 1928 - 1970

Underground transportation of mineral, waste and supplies is a vital function in mine operation. For this reason the selection and design of a mine car is important. Each type of mine car is constructed for a certain type of job. The design of a mine car is the result or product of the many people connected with its construction. It is the purpose of this report to bring forth many of these ideas by way of discussions, statistical classifications and drawings of the mine car.

The Venturi-Mucker, Don A. Rohrenbach May 1955

The Venturi-Mucker, Don A. Rohrenbach

Bachelors Theses and Reports, 1928 - 1970

Shaft sinking has been and still is one of the biggest bottlenecks in any mining operation. Consequently, the shaft is by far the most expensive and time-consuming excavation of any development program. When the shaft-sinking problem is broken up into its components, it is found that shaft mucking represents the largest fraction, both costwise and timewise. Since the mucking operation is the most important part of shaft sinking, it is, then, the most logical place for the introduction of cheaper methods.

Drilling And Drilling Trends In The United States For Mining, Sidney D. Cooper May 1955

Drilling And Drilling Trends In The United States For Mining, Sidney D. Cooper

Bachelors Theses and Reports, 1928 - 1970

This thesis, which is a requirement for a degree in Mining Engineering, emphasizes many current drills and drilling trends; however, without a complete discussion of the numerous factors that effect drills and drilling the reader would still be at a loss in selecting a drill to fit his particular need. With this purpose in mind, I have first attempted to discuss the many variables which must be considered and this is followed by the various types of drilling and drills.

Hydraulic Shaft Mucker, Frederick D. Owsley May 1955

Hydraulic Shaft Mucker, Frederick D. Owsley

Bachelors Theses and Reports, 1928 - 1970

Until recent years, mining has depended upon the muscles of men to supply the power required to obtain ore. With the rising cost of labor and the increased demand for metals, mine management has turned to machines to meet these demands. With the coming of the machines, the mechanization of mining began, and a new era in mining developed. Great strides have been made in drilling, hoisting, haulage, etc; but the sinking of shafts still create a costly operation.

Prospecting For Uranium In Montana, Louis Karhi May 1955

Prospecting For Uranium In Montana, Louis Karhi

Bachelors Theses and Reports, 1928 - 1970

Atomic Energy Commission releases reports of investigations such as RMO, RME, TEI and TEM reports, etc., also releases airborne anomaly maps. Various libraries and A.E.C. offices have these reports on file. The Montana School of Mines library has maps, various reports on the mineral industry, and receives reports prepared by or for the Division of Raw Materials of the A.E.C. Certain other libraries are designated as official U.S. Atomic Energy Commission Depository Libraries and receive copies of all types of unclassified reports.

Leaching As A Method Of Mining Uranium, Rob L. Kane May 1954

Leaching As A Method Of Mining Uranium, Rob L. Kane

Bachelors Theses and Reports, 1928 - 1970

This paper presents a new method of recovering uranium ores from the earth. By sinking drill holes into ore bearing beds, aqueous leach solutions can be circulated through the ores. Solutions of sulfuric acid, potassium carbonate and many other available reagents will put the ions of uranium and vanadium into the liquid leach. The pregnant solutions are then pumped to the surface so a recovery of the valuable portion of the ore can be made.

Shaft Sinking Investigation, Harold Foss May 1954

Shaft Sinking Investigation, Harold Foss

Bachelors Theses and Reports, 1928 - 1970

This paper, investigating shaft mucking, has been prepared as a partial requirement for the degree of Bachelor of Science in Mining Engineering. In the following material I have attempted to collect and compile all available information on mechanical shaft mucking, to compare and contrast the different methods and to trace their development through to the latest innovation. This development of the investigation is purposely being used to lead to a new method which will be discussed hypothetically as a conclusion to the paper.

An Investigation Of A Dustless System Of Dry Drilling, Norman J. Hardt May 1954

An Investigation Of A Dustless System Of Dry Drilling, Norman J. Hardt

Bachelors Theses and Reports, 1928 - 1970

For many years the problem of removing dust particles while drilling dry has confronted the mining and construction industries. In areas where water is not available, rock drilling is still being done under hazardous dust conditions. It was in an attempt to find a partial solution to this problem that the material contained in this report was compounded.

Application Of The Rotary Principle To Underground Mucking, Walter J. Smit May 1954

Application Of The Rotary Principle To Underground Mucking, Walter J. Smit

Bachelors Theses and Reports, 1928 - 1970

Since the beginning of man's utilization of rocks and minerals, he has felt a need for an efficient mover of these materials. Thus, he turned from the sole use of his hands to the development of the shovel, and through the other hand tools-- the hoes, and the fork, and the rake-- he finally came to the manufacture of the heavy, more efficient, large-scale rock movers-- the muckers, and the scrapers, and duckbill loaders.
