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.

Bachelors Theses and Reports, 1928 - 1970
This paper, investigating shaft mucking, has been prepared as a partial requirement for the degree of Bachelor of Science in Mining Engineering. 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.
