Practical Coal Mining by Boulton
A few years ago I came across five of the six volumes of this book in a
used bookstore in Calgary. I walked out of the door of the store with the
five of them for $10 Cdn. I am missing Vol 5. The volumes were published in
1907 with the exception of Volume 6 published in 1909. Volume 6 contains a
chapter on Coal Screening and Picking. I will get back with any information
on coal sizes. Incidentally, the main reason for acquiring these volumes
was the wonderful reproduction of paintings of mining scenes at the front
of each volume.
With kind regards,
Lawrence Chrismas
