Synopsis Many persons hold the opinion that the metal industries are fortuitous and that the occupation is one of sordid toil, and altogether a kind of business requiring not so much skill as labor. But as for myself, when I reflect carefully upon its special points one by one, it appears to be far otherwise. For a miner must have the greatest skill in his work, that he may know first of all what mountain or hill, what valley or plain, can be prospected most profitably, or what he should leave alone; moreover, he must understand the veins, stringers, and seams in the rock. Then he must be thoroughly familiar with the many varies species of earth's, juices, gems, stones, marbles, rocks, metals, and compounds. He must also have a complete knowledge of the method of making all underground works. Lastly, there are the various systems of assaying substances and preparing them for smelting; and here again there are many altogether diverse methods. Georgius Agricola, De Re Metallica, 1556. Just as Agricola documented the business of mining as practiced in his time, Underground Mining Methods; Engineering Fundamentals and International Case Studies presents the principles and techniques in use today. Reflecting the highly international and diverse nature of the industry, a series of mining case studies is presented covering the commodity range from iron ore to diamonds extracted by operations located in all corners of the world. The book is certain to become a standard for every practicing mining engineer and student alike. 001 0873352009
