An Investigation Of Ground Pressure By Scale Model, Theodore F. Berthelote
An Investigation Of Ground Pressure By Scale Model, Theodore F. Berthelote
Bachelors Theses and Reports, 1928 - 1970
This report includes a brief survey of the literature pertaining to the application of scale models to the study of ground pressure, a discussion of the theory of scale models, description of model material and loading devices used in this study, and a discussion of results obtained in actual experimentation.
Shaft Mucker Design, P. J.G Du Toit
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.
Modern Hydraulic Filling In Underground Metal Mines, Rainer Gevers
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
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.
Prospect Drilling, George Allen Mealey
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.
Underground Concreting, J. D. Riggleman
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.
Mine Cars Of The United States, Edward Sadar
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.
