"In the transition from hand-loading methods in coal mining to mechanical loading methods various types of equipment have been developed to do the same job. Among the coal mining operators and among miners in the coal fields, various equipment preferences have developed. This produces a sharp difference of opinion. emotional statements of such ideas based upon personal likings do not contribute materially to coal mining progress - it merely serves to confuse the issue. The author feels that the opinions on the loading equipment should be based upon some factual data rather than the preconceived idea. Often it is difficult to obtain such data that would give a clear-cut picture of certain equipment; and often it is not always easy to analyze facts after they are obtained so as to provide unquestionable correct conclusions. Direct comparison of loading equipment cannot be made in operating mines because to do so the loading units must be working in the same territory and under identical conditions. A general comparison however, may be made by analyzing the performance study made by making time-studies of the operating units"--Introduction, page 1.
