Hey guys,

http://mapapps2.bgs.ac.uk/coalauthority/home.html

It's an interactive map made by the Coal Authority, there is an option on there 'Mine Entry' if you click this it shows loads of X's on the map, just wondering what this actually is and is it showing you actual mine openings or CLOSED mine openings.?

Thanks,
Tonto

It shows the position of known (and inferred) mine entries (shafts or adits) extracted from a variety of sources including abandonment plans, other working plans, ordnance survey maps, geologists notes, company records etc.

Some may be open, some will be sealed (capped, filled, gated etc), some may have been removed by opencast mining or other developments and some will just show an approximate position

Well... I have to say that's pretty helpful for mine explorers. As atleast where I live it shows approximately 100-150 different adits / drifts which show no fillings / treatments. This could be very helpful.

Thanks,
Tonto

You`ll be lucky to find that number not sealed.

Don't be misled by "treatment indicator - false"! It doesn't mean they are still open, just that no details of sealing are known. Even some earlier NCB fillings show "false" because the records were incomplete or lost.

Hi,

I understand that and I don't expect every single adit to be open but always nice to walk along the mountain and check, especially on a nice day. What's the worse that could happen, it's shut 😃, I will just enjoy the scenery and find a different one to visit. :D

Thanks,
Tonto

I'm glad to see it's back, it's been offline the last few times I've looked and I feared it had gone for good. The format has changed slightly and I'm sure there are more mine entries listed than there were before.

http://www.arcgis.com/home/webmap/viewer.html?webmap=4dd36c2443904e1db7116355d4eccde3 , but that doesn't seem to work any more. I've also had limited success by taking a screen grab of a section of the CA map and lining it up on Google Earth. The adit listings tell you which direction the adit heads, so you have a fair idea it will be in a section of the hillside or cliff face that faces the opposite way.

Hi Tonto

The Interactive Map Viewer is designed for people to have an overview of the potential risks from coal mining when considering building or development.

Whilst it’s great to see you’re interested in historical coal mining and the legacy this has left on our landscape, we really need to make sure you’re aware of a couple of things. Abandoned coal mines have many dangers, some of which are not obvious but can quickly become life threatening. The Coal Authority, as the owner of the majority of coal mine entries in Britain, has a public safety responsibility to prevent accidental and unauthorised access into mine workings, which is also trespass.

Many thanks,
The communications team, Coal Authority

And this is what happens. When you ignore our advice about how to proceed about this type of thing and post on an open forum for all to see!!! Top work... :smartass:

We have been using the CA map to find old coal mine shafts locally. Several of them now have had an exposed raft over them or are covered. To check if they are shafts I have been using a 'Dowsing Stone' over the slab and this has been indicating there is a mine shaft. You have to take several readings to find the position. On open patches of land between houses where there is a shaft, I have Zigzagged across the site to find the position. The shafts we were looking for are on a Council Estate and plots have been left where there is a shaft.
We are only looking to confirm we have found the shafts to mark on a mine map.
I can recommend 'Dowsing' for finding shafts in this way. My friend with me had trouble doing it.
PM if you want details on how to use the stone. I have used it in combination with a pointer to find covered adits.
