Work by Drury and associates showed that reverse Polish notation calculators (RPN) were superior to algebraic notation (AN) calculators in terms of speed and accuracy of operation. This superiority may have been due to cognitive differences in operation or to differences in number of keystrokes used

โฆ Synopsis
obtained from other well-known sources. For example, in the chapter on the design of underground openings a considerable amount of material appears very similar to that in Obert and DuvaU's Rock Mechanics and the Design of Structures in Rock. However, the author does attempt to adapt this information to coal mines.
The first two chapters are on mining methods applied to coal mines, however most of the terminology directly relates to many other types of underground excavations and thus is informative to those uninitiated in mining methods. My general conclusion is that the book can be useful as a reference and as a textbook and particularly because it is one of the rare sources of compiled information on field instrumentation and laboratory test methods.
