Mining: The Classic Mine Technology Book from 1907
The technology of mining is the subject of this fascinating book, and two companion volumes, all of which were originally published in 1907. Mining: Drainage details the systems used to evacuate water from the mine. The book contains over 60 pages of text, numerous illustrations, and a set of examination questions for the mining sciences student. It contains chapters about surface drainage, underground drainage, hoisting water, pumping water, dams, siphons, and working in inclined and flat deposits. This historic book has been reprinted in its entirety. It┐s a treat for anyone who ever worked underground, or for anyone who ever wondered, ┐How does that work?┐
