Coal Mine Safety Engineering, Charles F. Herbert

Professional Degree Theses

"The progress of coal mine safety may be compared to the development in mining through the years. When coal was first discovered centuries ago, it was taken from river or creek beds and from the outcroppings on the sides of hills. After removing the most accessible coal from the surface, it was necessary to mine the coal by quarrying or stripping the overburden from the coal seams. It is reasonable to assume that when such operations began, accidents of a serious nature also began to occur. Such accidents were no doubt due to rolling rocks or stones, falling material, and …

The Scope Of Functions Delegated To The Engineering Department Of A Typical, Progressive Metal Mine, Alvin William Knoerr

Professional Degree Theses

"Nearly every conscientious engineering student will subject his college courses to an occasional critical analysis in an effort to assure himself that the studies he is pursuing will be a valuable aid to him in future practice. Possibly this skeptical attitude is accentuated by published letters of graduate mining engineers who decry the courses of mining schools in general and clamor for more practicability and higher specialization. Pure science as it is taught may at times seem to be very remote from any possible practical application. Mathematics may appear to be highly abstract. It seems quite logical that the degree …

Dewatering & Rehabilitating The Oronogo-Webb City Mining Area, Robert Knox Stroup

Professional Degree Theses

"The object of this paper is to describe the dewatering of the Oronogo-Webb City mining area, and the subsequent mining operations which were carried on in the northern section of that area. It deals with the development in that district during the time the writer was familiar with operations there; i.e., from 1935 to 1939, inclusive, and no attempt is made to describe the open pit mining and local milling which have been carried out as a latter part of this same project. Also, no attempt is made to describe the surface drainage work which was planned and carried out …

A Preliminary Report On The Placer Gold Deposits Of The Rio Acandi Seco, Choco, Republic Of Colombia, South America And A Possible Method Of Their Exploitation., Emmett Lee Arnold

Professional Degree Theses

"This property covers the valley of the Rio Acandi Seco, in the district of Acandi, Intendencia (Territory) of Choco, Republic of Columbia, South America.

It consists of four claims, or pertenencias, each straddling and paralleling the course of the Acandi Seco River. Each claim is two kilometers in width, one kilometer on each side of the stream bed, and five kilometers in length, making an area two kilometers (1 1/4 miles) in width by 20 kilometers (12 1/2 miles) in length, containing about 10,000 acres, the conversion being only approximate. These four claims are shown on the attached map as …

Essentials Of Rock Drill Design, Lister Merriken Cummings

Professional Degree Theses

"The earliest history of the rock drill is obscure and only fragmentary evidence concerning it is recorded in the Patent Office. However, no other tool has played a more important part in mining and excavating work. There have been two general classes of pneumatic rock drills -- the reciprocating, or piston machine, and the hammer drill. Fowler played an important part in the early development of piston machines, and the first hammer drill was made in about 1895 by a man named Brothers"--History, page 1.

Organization Of Geophysical Parties For Foreign Exploration, Charles Howard Dresbach

Professional Degree Theses

"Special conditions encountered in much foreign work make it necessary to consider many factors which are not encountered in domestic programs of geophysical exploration for oil. Although extremely difficult working conditions are frequently met in domestic operations by company and contract crews, the large store of past experience, the availability of fresh supplies, replacement or new equipment, and the proximity of the helpful home office make their surmountal more or less a matter of routine. Contrariwise, foreign operations are frequently conducted under much more difficult conditions, supplies and equipment can be secured only after long and costly delays, and the …

The Management Of Mobile Loading Units In Mines Working In Number V And Vi Seams Of Illinois And Indiana, Kirk Vern Cammack

Professional Degree Theses

"The knowledge and skill a face boss must have today is far beyond that required of even a mine foreman in hand-loading days. the care of material, the direction of the working force, the care and maintenance of equipment, the provisions for the safety of the men: all these are problems requiring the best of a boss' efforts. Because of these factors, the maintenance of a constant tonnage today rests almost directly on the section foreman. With this in mind, the following material has been prepared from the viewpoint of the face boss rather than from that of a superintendent …

Some Effects Of Geology On The Relation Between Rainfall And Run-Off, James Smythe Reger

Professional Degree Theses

"For the past five years, the writer has been engaged either directly or indirectly in the investigation of water supplies. Studies and observations made in Texas, Oklahoma, Colorado, and New Mexico, have brought to his attention the importance of geology to hydrology. This is especially true in reference to the relation between rainfall and run-off. In all texts and other publications relating to hydrology, the importance of geology to the subject is hardly more than mentioned. In the absence of actual stream flow records, many engineers resort to either the "direct comparative method", or the "rainfall percentage method", in estimating …

Construction Of A Concentrating Plant In The Waco Area Of The Tri-State District, William Henry Backer

Professional Degree Theses

"Company: St. Louis Smelting and Refining Company...The fee is some five hundred acres of mining land is owned by the company, and an additional two hundred acres is held under a mining lease. Drilling had proved the ore to occur in a dolomitic horizon and to contain from 3 to 12 per cent zinc and small quantities of lead. Early in 1930, some thought was given by the officials of the company to the erection of a concentrator to mill the ore from this acreage. During the ensuing months a basic flow sheet and type of structure were tentatively approved, …

The Design And Equipment Of A Model Coal Mine For The Union Pacific Coal Company, Superior, Wyoming, William Thomas Sharp

Professional Degree Theses

"In order to replace several mines in the Superior field that are near completion, the Union Pacific Coal Company have opened up the D. O. Clark Mine at Superior, Sweetwater County, Wyoming. They first contemplated opening up the individual seams from the out-croppings. This would have necessitated moving the present camp of Superior several miles west of the present site and building several miles of additional railroad. This plan was abandoned because of the burdensome cost. Then the idea was conceived of driving rock slopes down against the pitch of the various seams. By doing so, they could locate the …

Reopening An Abandoned Tri-State Zinc Mine - Waco, Missouri, Edgar Carroll Long

Professional Degree Theses

"Early in the year of 1937, the company employing the writer decided to reopen an old mining property located in Kansas, one and one-quarter miles west of Waco, Missouri. This property is known as the Grasselli No. 1, the lease of which had been acquired a short time prior to the depression of 1930. This property had been extensively mined on upper levels (195-foot, 176-foot, and 150-foot) by former operators and was a noteworthy producer of sphalerite. It was worked from the time of the beginning of the World War until about 1928. The lowest level, 285-foot, had hardly been …

The Latouche Mining Method As Used At The Alaska Juneau Gold Mine, Willard Alexander Gallemore

Professional Degree Theses

"The Latouche Mining Method has been used at the Alaska Juneau Gold Mining Company only since 1933, and is used in that part of the mine below the main tramming level. It consists of a series of radiating "long holes" (21 feet) drilled from stope raises, over the back of the stope. These holes break the rock into the stopes, from where it goes through bulldoze chambers to oreways leading to chutes on the No. 10 level. On this level, the ore is drawn into Granby Cars, trammed to the Main Shaft, and hoisted to No. 4 level. On this …
