I am looking at collierys in North Wales. The first list that I am putting on the forum is for Anglesey. First is the collieries name followed by the parish. Anglesey Coal, Llanidan. Berw Colliery, Llanidan. Berw Uchaf Colliery, Llanidan (also called Tai Hirion Colliery) Dafarn Newydd Colliery, Llangristiolus. Esgefiog Mine(coal) Anglesey. Gaerwen Syndicate Coal Trials, Llanidan. Glan-y-Morfa Colliery, Anglesey. Glantreaeth Colliery, Trefdraeth. Gwaithglo Colliery. Holland Arms Colliery, Llanfinhangel. Llangeinwen Colliery, Llangeinwen. Maltreath Colliery, Trefdraeth. Maltraeth Marsh Colliery, Trefdreath. Marquis Colliery, Llanidan. Menai Colliery, Trefdraeth. Morfa Mawr Colliery, Llangafo. Nant Colliery, Anglesey. Nantporth Colliery, Anglesey. Nineveh Colliery Anglesey. Paradwys Mine (coal) Anglesey. Pencrug Colliery, Llangristiolus. Penrhyn Colliery, Anglesey. Pentre Berw Colliery, Anglesey. Pont Marquis Colliery, Trefdraeth. Trecroision Colliery, Anglesey. Tan-y-Rallt Colliery, Llangristolius. Trefdraeth Colliery, Trefdraeth. Tyn-y-Fflat Colliery, Trefdraeth.
That's an amazing number of collieries for Anglesey, I knew that there had been some coal mined there but never realised that the it had been on such an extensive scale. What sort of dates where these collieries in production, methods of working etc? have I dreamt it or did I once read that some of the Anglesey coal had been naturaly converted into coke in situ?
I wasn't even aware of coal in Anglesey!! Was there any operating at Vesting Day?? If so did the NCB keep them open and for how long??
I was sent a complete list of all pits taken over on Vesting Day, the organisation of the NCB into areas and divisions by a gentleman in Wales. Of all the NCB's Divisions, South Wales appears to have the most collieries. Took me ages to organise the page's for the new website, hundreds of the buggers and little information on them either. So I have to research everyone for any info I can glean out of the internet.
Daz, natural coking was common in the NSW southern coalfield where volcanic activity occurred millions of years back. They called it "sintered" It was discarded by the company I worked for, Australian Iron and Steel.

The Anglesey Coalfield is under the Maltreath Marsh area, it runs from the sea in the west almost to Llangefni in the centre of the island. There where 4 seams worked there, the 3ft, the 4ft, the 6ft and the three quarter yard. The seams dip North West to North East at approx. 1 in 2. The coal was a very poor quality and it was semi coked. This was due to igneous intrusions running through the area. Water was also a big factor for failures. At least one colliery had to bring in coal from outside the area because its own coal was not any good for the pumping engine boilers. The copper smelters at Amlwch refused to use the local fuel because of the poor quality. It is recorded that very small amounts of coal where produced from the 1400s onward. During the mid 1800s several larger pits where sunk. None where very successful due to water and coal quality. Berw Colliery was recorded as producing 4500 tons for the year 1857. Some records say that all production had ceased by 1871 but Berw Colliery and Pont Marquis where still in the mine lists for 1880. In the book The Mineral Wealth of Wales and its Exploitation it states that there are fourteen seams of workable thickness. This could be a go back to an early capital raising scheme when the early developers in the 1800s stated that the Anglesey coals where better than Lancashire Coals. No coal has been worked there since the late 1800s.
