simple question: What is the real name of the mine that the New River Mining Co. kit is based on? I know its the D&RGW, but i can't find it anywhere..... ive been searching google for like, at least half an hour trying to find it, and I can't
arghh!!! lol
The prototype is identified in Kalmbach's book on coal railroading. I can't seem to find my book, but I'm certain someone out there can and will provide you the info.

It's the Edna Mine, on the DRGW's Craig Branch. Pics can be found on page 67 of TK's Guide to Coal Railroading.

The Edna Mine was an open pit, and the mine-run coal was moved over an intervening ridge by a closed-in conveyor belt line. Not only has the mine been closed and reclaimed, but the breaker and even the rails have been removed. Looking at current satellite views is frustrating to anyone who isn't a photointerpreter.
Chuck (Modeling Central Japan in September, 1964 - with a kitmangled Edna Mine)
The coal processing plant for P&M's Edna Mine (the name the coal mining industry uses to describe this structure) was a McNally-Pittsburg design. McNally-Pittsburg designed and fabricated more than 1,000 processing plants for the U.S. coal industry during the 1910-1970 period. The design dates to the mid-1950s and is appropriate, at least externally, for practically any coal processing plant for bituminous coal built during that time frame anywhere in the U.S. The Edna mine did not have coal-washing capabilities, which were very common for bituminous mines in the Illinois Basin (western Ohio-western Kentucky-Indiana-Illinois) during that period, and for coal mines supplying metallurgical coal from the western Pennsylvania, eastern Kentucky, West Virginia fields. Few western mines had wash plants beyond those supplying met coal. The coal wash plant will easily double the size of the processing plant. The Edna mine had only coal crushing, coal sizing, and coal loading capabilities. It was built at the very end of the era of domestic coal (used for heating homes, schools, businesses) and thus still had capability to size coal for open-grate firing. By the early 1960s that market had vanished and the Edna Mine then just loaded 2x0 steam coal. Most of its market was power plants in Denver and Colorado Springs, and cement plants and small power plants as far east as Indiana.

I am working on making a realistic interior for this model and and researching the interior of the original. Any one have any pictures or knowledge about this mine?
Did you try googling "Edna Mine" then clicking images? The aforementioned Kalmbach Publishing The Model Railroader's Guide to Coal Mining would be a helpful resource for you, as well.

Time...It marches on...without ever turning around to see if anyone is even keeping in step.
Class5I am working on making a realistic interior for this model and and researching the interior of the original. Any one have any pictures or knowledge about this mine?
Disclaimer... This is all supposition based on my experience working in open mines.
The building in the "New River Mining Company" is not the mine at all. It is most likely a processing building that probably is a condensed version of the prototype.
The building would have likey housed a crusher, washer, sorter (power screen), and conveyor. Maybe less, maybe something additional. The building is basically a hood.
Here in Florida, most of these machines are out in the open, no need for buildings to cover them.
Some of the interior would probably look something like this:

Living the dream.
A typical mine might only have an ore crushing plant, a dryer, and a storage bin under which trucks load and take the ore to a railhead, or it's delivered to a mill reasonably close...40 miles, maybe? But also typical would be the mill itself. There would be autogenous mills, or at least rod mills, ball mills, and possibly a cyclonic apparatus to sort effluent from the ball mills for re-grind. From there, the effluent goes to thickeners, and then to flotation circuits which separate the minerals from the tailings. Again, there'd be a dryer (the buyer of the concentrate would rather not pay to ship water, all things considered, and the contract would state the maximum and minimum water content of the concentrate).
Point is, depending on the 'size' of the mine, the daily tonnages processed by the crusher, you might have it all under one large building. Typically, though, the fine ore bin, the last step before the grinding circuit in the mill, is a large building all by itself. It would have a number of conveyors working in it. Some crushing plants are below ground. From there, the crush is taken by conveyor, rising out of the ground, to a point up high near the roof of a fine ore bin.
Various searches at the Library of Congress may help:

If you can access Flickr there many interior photos, many after abandonment, though, of different coal washers and breakers.

Good Luck, Ed
Wow, great info everyone very helpfull. Keep the info comming! I will post some Cad designs that I am working on as I complete them
