"The purpose of this thesis is to provide a suitable basis for comparing the relative advantages of the friction and drum hoists under various conditions of operation.
Such comparisons are mainly and necessarily based upon physical characteristics of the mechanisms for lack of appropriate economic data. It is believed, however, that this inadequacy may be alleviated to some extent by substituting comparative theoretical energy requirements of' the two hoisting systems under identical duty conditions over a practical range of mining situations involving various depths and daily productions.
This has been accomplished by adapting a computer to standard mine-hoist design techniques and utilizing basic data that are accepted by pertinent authorities.
The results are gratifying in that they do indicate areas of advantage for each of the heisting systems within the span of operations considered"--Abstract, page ii.
