Attached gives a bit of info regarding the sad demise of a quarry worker from Budle Crag - (the sort of stuff people like to read about the Mining & Quarrying industry).
http://www.dmm.org.uk/colliery/b811.htm A good place to see a modern whin stone quarry in action - try Barrasford, Gunnerton etc - on the North Tyne - a few miles above Hexam, or the quarry at High Force - Teesdale. The technology will not have changed that much from the days of Budle Crag (the early 1900's) etc. My father worked with a stone crusher in a sand and gravel quarry from the 1950's - 1970's that was built circa 1900. When the quarry closed it was removed and sent to another quarry, very durable bit of kit is a crusher.
Beamish Museun put on a display at times using a mobile crusher with a steam engin, bit of track with a couple of 24" locos, and the boys play at being quarry workers, gives a good idea of how primative these things actually were.
Have you had a chat with the people at the Mining Institute at Newcastle - perhaps thay may have some liturature that could held your work.
(Gentle hint - it is best to place the name of the Mine / Quarry in the "Subject" - along with any nearby the town /county)
