As far as I know the Somerset coal field is the only one which has records including a photo of a pit worked wearing a belt and chain with a hook, used to man haul tubs along tunnels where the roof height was too low for either ponies or tram tubs. Mind you a lot of the Somerset pits couldn't use ponies as the shafts were narrower than the standard in the rest of the country. About a foot or 18"" is really the limit of economic extraction - narrower seams needed so much rock cutting to get the coal out that it wasn't woth the effort. -----Original Message----- From: British archaeology discussion list [mailto:[log in to unmask]] On Behalf Of Andrew Smith Sent: 26 October 2007 08:26 To: [log in to unmask] Subject: Re: [BRITARCH] Silbury Hill As far as I can see there has been no practical response to Cerridwen's comment about the design height of coal workings. The height of the working is surely determined largely by the depth of the coal seam. In the Somerset and Gloucestershire coalfields, I believe that seams as narrow as 18 inches were worked by miners lying on their sides. Also, if one is not familiar with Tolkien, the dwarves did not apparently let their physical size limit the scale of their excavations under the mountains.
