    Caving with a joint replacement

    Not exactly a replacement but a bad repair. I had a mining accident when I was 30. I broke my femur just at the point where the shaft joins the ball at the top. It was operated on and a blade and plate screwed to it . I was off work for 13 months whilst I learned to walk again. My main problem...

    Handheld 3D scanning - move over disto?!

    You can do 3D stuff with your iPhone. All the latest ones and iPads have a LIDAR sensor built in. Google Polycam app and you'll find it and other similar apps. Mainly aimed at building engineers for creating drawings and walk-throughs.

    Operation Mole Mines Research and Exploration Group Contact Details?

    Nick Butcher is still around, saw him at a funeral a month ago. However, he was never OM, he has been PDMHS since the 60's with a bit of TSG later. There are some OM around but I don't have contact details. John Wilmot is one. He was on AN but I don't think he has got here yet?

    Dig Face Ventilation

    Try a battery powered leaf blower connected to polythene lay-flat tubing. The easiest tubing is food packaging stuff that comes in rolls. It is meant to be cut and heat welded with food in but you can roll out what you need and just let it sit on the floor or hold it up in the roof on springy...

    Rescue of dog from a mine shaft at Winster - 12th Feb 1963

    I wonder if that was the same Doug Fearn who was a photographer for the Matlock Mercury and Derbyshire Times in later years?

    Orgreave Rally

    Sadly, I feel that the whole thing was not about class wars or downtrodden masses but all about Scargill’s ego. The coal industry needed to scale back. You can’t keep mining the same pits forever, they do run out. However, rather than work sensibly towards a gradual reduction over several years...

    British Fluorspar

    They certainly did. My first mining job in 1971 involved going up to the Ryder Point plant to watch the incoming ore from Deepwood Mining Company being sampled by the Guiulini people as Deepwood didn't trust the analysis and thought they were being diddled. All the lab staff were Italian.

    Lamp & Check Meet - South Yorks

    That type of lamp was not around in the Nystagmus days. That is a comparatively modern lamp. No idea about the glass but I will try my lamp with UV, just for fun!

    Wrysgan Purchase

    That will be a problem for the outdoor centres. It is a favourite venue for many of them and was/is inspected every year for the purpose.

    Lamp & Check Meet - South Yorks

    Correct. I don't know why I said Acme. I have a Hardy pick in my shed with the name cast into it...

    Lamp & Check Meet - South Yorks

    The blade size will vary as they were resharpened. The whole idea is that a collier could knock back the wedge and remove the blade. He then took the blade up with him at the end of the shift so it could be sharpened for the next day. They were sharpened by the blacksmith, heated and hammered...

    I rather think that Miles' site got overtaken by him starting his Go Below business and finding no spare time to do anything else!

    Aditnow.co.uk

    Aditnow was very good because many of the photos were uploaded during discussions and so had context and folk could add extra snippets of information to enhance the value of the photos. A bland database is OK but it really needs a forum bolted on for discussion.

    film of 1968 hand winching Seedlow mine. by Pegasus Caving Club

    The chap with the red ammo tin is on a short belay to the main rope shackle. Having said that, the short belay looks like it is bailer twine and that's old bailer twine, not modern polyprop stuff! I never liked the idea of lowering on a brake band as done in the film. PDMHS always lowered by...

    Isle of Man accessible mines?

    Pete, That’s a lovely photo of the forepoling in the main adit. Terry and I did that in the early 90’s when we were contracted to the IOM government to re-open the adit. Les

    Carbon dioxide

    Sorry for the late reply, I am abroad on hols at present and missed things. However, I have still been exploring. Did anyone see the Aditnow Facebook post about the iron mine in France near Nancy? We went last week, interesting place. Bad air in mines is a fascinating subject. Over the years...

    Name the objects

    I would agree, looking at the shape of the bottom end , it looks like it was curving round like the other end. Possibly some sort of cable support bracket? No idea about the age of the lamp. However, it is a very old design. In 1981 my wife found a pottery lamp of the same design in a Roman...

    Mining engineer questions

    We had to install a lot of tell tales at Dragonby. They consisted of long wires up to 8metres into boreholes fixed to traffic light coloured tubes. If the strata sagged, the wire pulled tighter and the tube showed a visible warning. They are easy to see as you travel past and if there is change...
