Book Description
Excerpt from Proceedings of the Second National Standardization Conference: Held in Connection With the Twenty-Fourth Annual Convention of the American Mining Congress, Chicago, Illinois, October 17-22, 1921 This is so universally true that one of the things that we can do for the mining industry is to improve their methods and practices in mine ventilation. It is not only of very great importance from the humani tarian standpoint but it is just as important from an economic standpoint. I have visited mines where they had a great, fine, modern fan that they were not getting twenty-five per cent. Efficiency out of. They were spending four times on current what it should cost to produce the amount of air that they were giving the mine. That is what we are trying to do. Whether the laying out of a metal mine for proper efficiency and economical ventilation is sufficiently identical with the best practices for a coal mine is for us to decide. My idea was that some special committee that we would form for other purposes as well could take that question under careful consideration, after they had read the report that was given by the two committees, see whether they are attacking the problems along the same line or not and the committee could then draw up some conclusion.
