Excerpt from The Design of Mine Structures The aim in writing this book has been to present a systematic dis cassion of the design of mine structures. While the design of head works for mines is given the principal place, the design of buildings, bins, coal washers and breakers, etc., is discussed as fully as the limited space permits. In the design of mine structures it is necessary that the structural engineer be familiar with the operation of mines and with various preparatory processes for ore and coal. The discussion of the operation of mines has been limited to the purpose of the structural engineer, and the design of hoists and other machinery has not been considered.
