I am preparing some information for a presentation, for which it would be really useful to have a photo from the 'Practical Coal Mining' book, however my book is at home, and I won't be able to get it before I need to finish this.
If anybody has a copy handy, and could send me a photo of the section on "Support of the Roof", specifically the diagrams of methods for driving in soft ground, I would be extremely grateful.
Please let me know if you can help!
Thanks in advance,
Sam T
