I first visited Jugholes in 1965. Back then there was a railway track in the main entrance (2nd Water Cavern) from near to the mine workings out onto the waste tip. Another ran from close by the end of that up through the wood to a loading bay accessed from Salters Lane. These must have been worked by winch and I cannot recall remains of anything similar down the hill, maybe where, or what, the 'ropeway' might have been.
The 'old man's workings' I entered back then fitted the description given in the posts above, with small stemples 'supporting' the roof in places but more on the floor. Small workings and packs of small deads. Stability was very "iffy". It was a long time ago but my memory of these places put them somewhere from the bottom of the climb out into the 2nd Water Cavern and heading towards the upper series. If I remember correctly there was a small stream in that part.
My first trip to the sump in the Upper series ended at a pool of green water, not the wet crawl I saw more recently. Our party back in the 1960s missed the hole in the roof near the sump, whatever was up there and anything else in that area; it was just a trip to the water at the end.
As schoolboys back in 1965 we calculated the depth of Hut Shaft to be a lot deeper that 20m, twice as deep by our reckoning but we could have been wrong! I have only met one person who has descended that shaft only to find it blocked with rubbish. I have never discovered who included it on the well known section of Jug Holes and who stated that it was the site of 'extensive caverns'.
What was there before quarrying and the collapse of the 1st Water Cavern has to be wondered about.
Other things to think about - the connection with Oxclose Mine, if Jugholes Sough ever reached Jugholes and the story abut out of work Millclose miners descending into Jugholes and emerging on the Via Gellia (or did they actually go prospecting, mine to mine across that distance).
Jugholes is certainly an interesting system.
