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.
