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

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.

A Simplified Mathematical Method For Petroleum Property Evaluation, Charles G. Edwards

Masters Theses

"The economic evaluation of a petroleum reservoir involves two fundamental operations; 1) predicting future production behaviour, 2) determining the present worth or this future production. This thesis purposes to eliminate the necessity of repeated calculation which is required in performing the second operation under existing methods.

Because the first operation, that of predicting future behaviour, is necessarily an estimate, there is an apparent tendency to employ approximate methods in the determination of present worth. The evaluation method developed in this paper confines estimation to the first operation, where it rightly belongs, and treats all subsequent work with mathematical exactness.The estimation …

Prospect Drilling, George Allen Mealey

Bachelors Theses and Reports, 1928 - 1970

This report covers four types of prospect drilling: churn drilling, diamond drilling, percussion drilling and calyx drilling. No other types of prospect drilling are discussed except these four types because any other method are not extensively used.

Shaft Mucker Design, P. J.G Du Toit

Bachelors Theses and Reports, 1928 - 1970

The mucking principle employed in the design of this mucking machine is that of a continuous operation instead of an intermittent one. The mucker was primarily designed for operation in shafts (vertical or inclined) and winzes but the mucker is not restricted to these.

Underground Concreting, J. D. Riggleman

Bachelors Theses and Reports, 1928 - 1970

Concreting has in the past few years become a prime consideration in underground support; therefore, this report will endeavor to outline some of the basic fundamentals of underground concreting. Greater emphasis has been placed upon the characteristics and criteria of good concrete and placing procedures and techniques. Actual examples of practice have been cited but only to illustrate the basic fundamentals which are outlined in the major part of this report.

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

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

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.

Subsurface Geology Of The Mississippi Embayment Of Southeast Missouri, John Gustave Grohskopf

Professional Degree Theses

"To the southeast of the Ozark Escarpment all municipal, industrial, and agricultural water supplies of record are obtained by drilled wells from alluvial sands and gravels, unconsolidated sands of the Wilcox and McNairy (Ripley) formations, and at a few towns from consolidated Paleozoic dolomites limestones, and sandstones. The irrigation wells obtain their water supply from the Allluvium. These wells have recorded yields of several thousand g.p.m, and the water, though excessively high in iron, is still satisfactory for the irrigation of crops. Some municipal and industrial supplies are obtained from the Wilcox sands, but the water usually requires iron-removal treatment. …

Development Of Large Hole Burn Cut Drift Rounds, Joseph J. Yancik Jr.

Masters Theses

"A decided change in the attitudes of mining management toward the need for mine research has taken place during the past decade. More emphasis is being placed not only on the improvement of existing mining methods, but also on the adaptation of new ideas. As the depletion of the high grade ore deposits in this country becomes a reality, the need for reducing the costs of mining is pressing. The successful exploitation of low grade ore bodies will depend upon the continued advancement in the science of mining.

The methods used today in driving a small drift or tunnel in …

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

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

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.

A Study Of Tunnel Demolition By Hasty Methods, Richard Lee Bullock

Masters Theses

"The use of explosives to construct obstacles which impede the enemy or close his routes of communication has long been employed by our armies. They have developed fairly effective methods for destroying bridges, setting up road craters and constructing abatis. However, one phase of obstacle construction, that of tunnel demolition, has been neglected in that no procedures or methods have been formulated which will aid in the proper destruction of tunnels.

At the present time, under the auspices of the Department of the Army, The Missouri School of Mines and Metallurgy is conducting a research program on tunnel demolition. The …

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

Bachelors Theses and Reports, 1928 - 1970

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

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

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.

The purpose of the study is to assemble into one volume information that is pertinent to the rehabilitation of tunnels. Notwithstanding the voluminous size of the paper, much descriptive material necessarily has been omitted because of the far-reaching scope of tunneling practices and of the specialized fields therein. An extensive bibliography has been prepared to supplement the material that has been selected for presentation. Through consultation with tunnel men of all ranks, observations in the field, and an intensive search …

Adaptation Of Diesel Rubber-Tired Loading Equipment To A Bedded Fluorspar Mining Problem, Robert Gill Montgomery

Professional Degree Theses

"The fluorspar-zinc orebody at Minerva No. 1 mine near Cave in Rock, in Hardin County, Illinois, would have been classed as non-commercial before the days of flotation milling and mine mechanization. The bulk of the ore requires fine grinding for acceptable beneficiation, and the assay of the head feed runs considerably lower than grades thought to be commercial in the fluorspar district prior to 1940.

However, the reserves found by drilling before the decision was made to invest in mine development, and the construction of a two-product, 250-ton, flotation mill, with complete power plant and surface shops, exceeded 600,000 tons. …

An Investigation Of The Use Of Surface-Active Agents In The Secondary Recovery Of Oil By Water Flooding, Robert P. Schafer

Masters Theses

"The importance of producing oil cannot be emphasized enough in this modem world. Therefore, when primary methods of production seemingly exhaust the oil reservoirs, a secondary method of producing more oil is a necessity. At the present time, secondary methods of oil recovery have developed into a large industry. They are not a new development. The need of introducing compressed air or air-gas mixtures into the wells to increase production was quickly realized. Water flooding methods followed, and at first were restricted to the Eastern fields. Later, about 1935, systematic water flooding methods were developed and applied all over the …

Plastic Deformation Of Rocks, Muhammed Abdul Waheb

Masters Theses

"The purpose of this investigation is to search for a method by which the strength properties of a rock may be described.

For this purpose, an attempt has been made to find out some relationship by which the rooks may be classified or described. For the solution of problems of mine stability, the mechanical properties of a rock should be known, i.e., hardness, toughness and strength. It is difficult to make a study of some method of classification or description of a rock without knowledge of these properties.

With a view to achieve the solution of a general classification for …

Marcasite From The Upper Mississippi Valley Zinc Area As A Source Of Sulphur, Carl R. Christiansen

Professional Degree Theses

"Sulphur is a mineral material which is as basic as steel to our industry and economy. This fact is not generally realized because it is seldom seen, but it goes into the manufacture of practically every article of clothing we wear, and the food we eat is dependent upon it. Most items we produce require the use of sulphur at some stage of their manufacture. The consumption of sulphur has been increasing rapidly and is now far above its World War II peak. Production has been greatly increased but has been unable to keep up with the increasing demand. This …

An Efficiency Analysis Of Underground Haulage In The Tri-State Mining District, Leroy King Wheelock

Masters Theses

"Purpose of Investigation: This study was undertaken to describe and analyze the system of haulage as practiced in mines of the Tri-State District by the Eagle Picher Mining and Smelting Company.

The investigation is concerned with all of the operations involved in moving the broken rock and is composed of three distinct procedures: loading, hauling, and hoisting.

One of the important items in the cost of mining is the movement of ore and waste to the surface for further disposition. Increased efficiency of transportation should introduce lowered production costs.

In this paper the efficiency of the present equipment and the …

Rehabilitation Of Land Stripped For Coal, Richard Matthaei

Masters Theses

"The usual connotation of the word rehabilitation as applied to land areas is the restoration of that land to its former efficiency. However, in the spirit of conservation that is essential to our standard of living, the word has begun to have added meaning. In the fullest concept, rehabilitation involves a study of soil characteristics and capabilities, and creation of productive uses of which the land was not capable in its original condition. The true conservationist has an opportunity to make a useful contribution to the future generations of this country. The United States Forestry Service and the United States …

The Application And Utilization Of Mining Models For Instruction And Display, William M. Shepard

Masters Theses

"The subject of the utilization of mine models for instruction and display at institutions offering courses in mining engineering has not been widely discussed in the literature. The value of models as visual aids in teaching has long been recognized, and they have been extensively employed by some institutions and by some instructors. However, the writer believes that a wider range of types of models are suitable for instruction purposes than have been employed in the past, and that mining models, properly arranged and adequately labelled, may be used in displays to give both the layman and the beginning student …
