Dear Chris,
I think you will find the Mining Journal of use. On my many journeys
amongst the MJ I have seen quite a few advertisements for coal cutting eqpt.
within same (1880's onwards). Likewise the Mining Electrical Engineer and the
Colliery Guardian (and other similar coal mining pbls. as the CG), will I am
sure be of use to you - also Mine & Quarry Engineering. Furthermore pbls.
& Insts. connected with mining electrical engineering - IMEE (most cutters
were elec., but there were one or two compressed air versions as I'm sure
you know anyway). I do not know very much about this subject, just things
seen along the way while looking for and doing other things.
Regards, Bernard
