Shaft Mucking Investigation Part 2, Jorge R. Delzo
Shaft Mucking Investigation Part 2, Jorge R. Delzo
Bachelors Theses and Reports, 1928 - 1970
By use of several digging principles, such devices as scrapers, clamshells, power shovel loaders, etc., have been perfected. The net results have been an almost complete elimination of hand mucking, an increase of loading speed, and a reduction of sinking costs. Moreover, the elimination of hand mucking has had a favorable psychological effect on the crew, as well as saving physical effort for the other phases of the shaft-sinking cycle.

Design Of A Portable Headframe, Rodney C. Foster
Design Of A Portable Headframe, Rodney C. Foster
Bachelors Theses and Reports, 1928 - 1970
Present day methods of ore exploration consists of surface geology, geophysical methods and drilling datum. These methods have all produced results, but, the sure way of telling whether ore is present is to look at it in place, determine it's tonnage, grade and ease of mining. This can only be done by the use of a headframe to sink a shaft. Therefore a low cost, well designed and easily constructed headframe would be a great aid to underground exploration work. For this reason the report is devoted to the design of a portable headframe to be used in preliminary ore …

The Adaptation Of An Ore Feeder To Replace A Chute, Donald M. Forsman
The Adaptation Of An Ore Feeder To Replace A Chute, Donald M. Forsman
Bachelors Theses and Reports, 1928 - 1970
I believe that by installing apron ore feeders in place of chutes, spillages, manual labor, and loading time could reduced, and greater safety and the average car factor could be increased. Although an apron feeder would be a considerable investment, maintenance should be very low and the feeder would be re-usable many times.
Shaft Mucking Investigation Part 1, Jorge R. Delzo
Shaft Mucking Investigation Part 1, Jorge R. Delzo
Bachelors Theses and Reports, 1928 - 1970
This paper represents an attempt to explain the operation of inclined-shaft mucking, and the machines developed for this purpose. It also covers some research done for the design of a continuous shaft mucking device, which could in the future prove to be the answer to this important problem. In many small or intermediate mining operations, where this problem has been a prime headache, the added costs of shaft mucking, because of lack of speed, and versatility, might very well mean the difference between profit and collapse.

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
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.

Hydraulic Shaft Mucker, Frederick D. Owsley
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.
Drilling And Drilling Trends In The United States For Mining, Sidney D. Cooper
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.
Leaching As A Method Of Mining Uranium, Rob L. Kane
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.

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.
