For some unknown reason, the thread got lost.

Stanhope Colliery (aka Furnace Main) and Stanhope Silkstone Pit or Shaft (Pumping station from 1929 to 1988) are up between, and just to the south of, a line between Cawthorne and Barugh Green.

Stanhope Silkstone Main (earlier name Thurgoland) is much further south at the bottom right of my map.

I've just posted a section of my map of the area in "Latest Mining & Mine Exploration Documents" that shows them both (and a lot more) - the status of this section is still "work in progress” as I've been concentrating on the Bowling & Low Moor area around Bradford and mines to the south and east of Huddersfield.

Thanks for that - the map is rich source of data.

Looks like Silkstone is a name often used in a number of locations - there's another Silkstone Main Colliery on my 1850 OS map just east of the Stanhope Silkstone Colliery (Thurgoland). Perhaps we'll have to start naming these mines with the locality in brackets to aid searching and avoid confusion?

Q: Silkstone, Silkstone, wherefore art thou Silkstone?

A: All oer t'oil

As well as being the name of a village in the area; the Silkstone Seam is a fairly extensively worked seam. This also contributes to Silkstone appearing in lots of names (i.e. Pit sunk to the Silkstone Seam). It was also used as a colliery company named.

---

I'm reasonably certain - maybe someone with better knowledge can back me up on this - that Silkstone is generally the name of the coal (seam) that was mined and less a reference to a particular location.

BTW: the most common mine names in Yorkshire seem to be Lane End and Victoria.

As I mentioned, the map is by no means complete.

My aim is to get as many mines (and named mines) on one map along with railways, ironworks and tramways - the basic background map may vary in vintage, but is generally early to mid 20th century with older or newer mines copied and pasted in in Photoshop. This period seems to be a good "mean" for getting working railways and many smaller mines on the map.

It may confuse some people that mines are shown that are either before or after the map period, but it is not intended to be one particular "slice" of history.

Main reference sources are freely available Coal Authority maps, BGS data, "Old Maps", the Leeds Tithemap Resource, online local/regional/parish magazines, railway walks, local history and industrial archaeology groups, recorded BGS mineral sites from local government surveys (planning permission) and genealogy groups - and of course, AN members and sources.

Glad to have helped

You are correct the Silkstone was a seam which outcropped and was probably first exploited at Silkstone but mined subsequently at many locations. It was one of several seams mined by my Dad's pit (Manvers in Wath).

Your map project is a significant one. My own interest is to extract old mine data from maps including some 1850 OS maps that I have and put that into AditNow so the information is shared and disseminated (and not lost when I depart this life). I use the Old Maps site when I need information on different periods. I'm plotting my mines as overlays in a digital mapping system (Memory-Map), and am sharing the overlays through my web site (shown in my AditNow profile). Yorkshire mines is an ongoing project.

As a former quality manager I'm keen to see that the database is accurate which is why I keep raising questions about the accuracy of some of the AditNow mine locations - this creates work for the moderators I'm afraid, but hopefully adds value to AditNow as a resource for explorers and historians alike.

The scientist in me also likes to provide corroboration for new sites that I upload, so I always upload a map extract where I have one free of copyright issues, or a reference to a specific edition of the OS map in the site description if I found it in Old Maps.

You may already know this. But oldmaps support urls of the maps centered on the coordinates (eastings, northings)?

For example converting the the database grid reference to eastings and northings
http://www.old-maps.co.uk/maptiles/m100392_430150_407350.png 

which shows the entry as close to a colliery but not centred where I would put it.

---

Thanks Dave - I didn't know that. Never too old to learn though 🙂

Is there a component of the URL which specifies the date or do you get whatever OldMaps decides to send?

---

That's not something I have noticed before, although the kind of thing I would normally pick up on.

Currently only 6 fig gridrefs can be entered in to the mine entry; although pin pointing through the map gives more numbers, however these gridrefs (from google etc) may be incorrect.
Occasionally I put a 10m gridref in to the mine entry description (this is taken as being the centre co-ords from Old Maps), or by putting a large map in to a GIS system

I make an overlay from sections extracted from the Coal Authority Demo website map as screen shots

http://mapapps3.bgs.ac.uk/coalauthority/homeiframe.html 

and lay this as a semi-transparent layer over OS map data in Photoshop to pinpoint the shaft locations and then start looking for the names that are not shown on the OS maps between 1850 and the present.

For map scale 1:2500, you need to enlarge it 8x and then fiddle around to match the details like roads, streams, rivers, woods, etc.

Maybe I'll get around to finding the exact enlargement factor one day.

Another often fruitful source is the BGS Borehole Records website - some of the records are for logs recorded in named mine shafts

Thanks Dave - I didn't know that. Never too old to learn though 🙂

Is there a component of the URL which specifies the date or do you get whatever OldMaps decides to send?

if we look at the example

http://www.old-maps.co.uk/maptiles/m100392_430150_407350.png 

m100392 is the map identifier

430150_407350 are the coordinates (eastings and northings)

pm me and I will reveal the dark art of getting the map identifier but it only takes a click

Something similar occurred to me - but I have not done anything yet.

The coal authority map is most excellent. It distinguishes between adits and shafts and also gives the bearing of an adit.

I was going to start with a screenshot and register as an overlay into GoogleEarth using the coodinates of the screenshot.

I was then going to compare the sites with the nmrs kml map for the same area.

There are lots of interesting problems in extracting the information automatically
