Talking of board & pillar: Heard a rumour that the bloke who owned Bestwood pit got permission to work B&P under part of Nottingham so as to cause little subsidence. However as the seam was being abandoned he robbed the pillars & of course there was subsidence. The authorities suspected what he had done but couldn't prove it as the seam had been sealed off. Heard that he bent the rules a bit..

(a) board and pillar (b) pillar and stall (c) room and pillar (d) stoop and room. The name varied depending upon the part of the country the mining took place, however the method was basically the same. Anyone know of any other names. Hey miners, this ist Fritz from germany, pre retired from mining since 3 years from now. Germans know this item as 'room & pillar', in german called 'Pfeilerkammerbau'. As a coalminer in the meantime my business has been the road heading. And for this item I am searching for some help and knowledge about an equipment that spent a littler time in germany in the older days. It was named 'Trackheader', build by 'Perard Torque Tension Ltd.'. Does anyone have informations like pictures, blueprints, an adress to aks there? Sorry, when e met the wrong part of this forum and sorry also about my hard english. Hoping on answers, Glückauf Fritz
I've always known the method as Bord and Pillar. |

None of my Geordie friends have ever heard of the word, "hetter" is Geordie for hotter, and a "heed board" refers to a cap or lid over the top of a prop. That's as far as they could help.

I've only ever worked in bord and pillar in 7ft and upwards Sam, lowest was around 6ft 6ins in gypsum, but mostly around seven feet. 15 feet in potash and around 8ft when I worked in collieries in NSW. But the full working thickness of the seams. I gather in thinner seams its worked the height of the seam with main roads driven in the dirt to gain height. It does have it's usefulness, in shallow workings it's impossible to work longwall, under water bearing strata the same. Plus if your working under cities/towns reservoirs and other sensitive areas, Bord and Pillar is the only way to extract coal. It does have drawbacks, in that it is hard to ventilate, you only get around 50% max extraction rates. It's not all that long ago when all coal in the UK was extracted by Bord and Pillar. |

About 1962, the mining dept organised a trip to Coppice Colliery at Cannock. The trip appealed to me for two reasons, first, Coppice or better known as the old fair lady, was consistently at the top of the pit overall oms leaque. 2nd Totally pillar and stall and 3rd it was the pit that was my fathers first pit.
the seam being worked was about 5ft 6ins thick, 10 man teams. system AB arcwall tracked middle cut with 6ft jib. 1 man then bores on and assists shotfirer, fill out with Joy loader. extend CW chain flat link chain conveyor. the team reckoned to do 10 heads per shift. supplies 2men +pony.
Back on the surface we were talking to the undermanager Ernie Mason, a real old fashioned Cannock man, when there came a knock on his door and 2 black faces appeared." Gaffer yove gotta do sumthin about our our ventilation when weve fired yo cant get in to fill out for 20 min" Ernie said in reply "Me and the missus decided to take a walk down Chase Terrace Sunday evening and we popped in the club for a drink. I looked in the bingo and yo were all in there and the smoke was as thick as a bag, but I day hear any complaints from yo lot. end of story. great visit, great characters.

Having only worked on Longwall faces, first with ploughs and then shearers, can't understand how Bord and Pillar works. It seems to me to be ancient history as it was only worked on the No1 (Beresford) seam which closed years before I started. Coal seams in Kent were narrow - if you have Bord and Pillar, do you work the "face" at the same height as the "gate" roads and take a lot of muck out with the coal as opposed to Longwall only taking the coal in the main? |

To fritz's post PTT designed an improvement on the Trackheaderandinstalled2 of them 1 in Hungary and the other in mine number 13 in Datong China, both were used for drivages and straddled a stage loader
I worked as a service engineer for them and spent 5 months in Datong maintaining the machine and it had its own built in track operated hydraulically along with a bucket for loading out.
It was a heavy strain in the cylinders which took a long time to get replacements but on the whole was a successful installation apart from roof control which sometimes meant bricking up the sidewalls with solid concrete blocks
This took place in 82 and I've since been retired for the last 14 yrs
