Mine	Region	Worked	Commodities
Taff Merthyr Colliery One of the last deep mines sunk in South Wales under private ownership, it became a flashpoint of 1930s industrial unrest when riot police were brought in.	Merthyr Tydfil	1922-24 (sinking)–1992	Coal
Tal-y-sarn Quarry As the neighbouring Dorothea quarry expanded, it grew to swallow the original village of Talysarn itself, forcing its relocation -- some of the old village's buildings remained in industrial use, and their ruins can still be seen today.	Gwynedd	1845–1934	Slate
Talar Wen Quarry A roadside quarry of five hundredths of a hectare, crowded with Llandeilo trilobites.	Carmarthenshire	ended by 1993	Limestone
Talargoch Mine At its height Talargoch's pumping plant ran to an 80-inch engine, a 100-inch Cornish engine and thirteen smaller engines simultaneously — a small industrial army assembled for one job: keeping 200 feet of waterlogged glacial gravel from drowning the mine beneath it.	Flintshire	From 1303–1884 (underground)	Lead, Zinc
Talk o' th' Hill Colliery A Talke colliery where two explosions six years apart killed 109 men and boys.	Staffordshire	—	Coal

Talnotry Mine Nickel mines are vanishingly rare in Britain, and Talnotry's spoil heaps are valued today less for what could still be dug out of them than for the mineral specimens already sitting on the surface — nickeline and gersdorffite unlike almost anything else in this archive.	Dumfries and Galloway	c. 1885–mid-1880s	Nickel, Copper
Talwrn Colliery The blast in No. 2 was strong enough to kill a horse in the pit next door, through the roadway that connected them.	Wrexham	by 1857	Coal

Tankerville Mine Tankerville's 1,690-foot shaft — the deepest anywhere in the Shropshire orefield — makes an odd kind of monument: a huge investment in depth chasing the richest vein the county ever recorded, defeated in the end not by running out of lead but by the price of lead itself collapsing under it.	Shropshire	From early 19th century–1911-13	Lead, Silver, Zinc, Barite
Tannochside Colliery Its owner opened a brand-new brickworks right next to the colliery in 1936, recruiting its entire workforce locally to turn out 150,000 bricks a week.	North Lanarkshire	1870–September 1945	Coal

Thorne Colliery Seventeen years to sink, and water beat it in the end — the pumps that had run since 1910 were finally switched off in 2004, forty-eight years after the last coal.	South Yorkshire	January 1925–1956	Coal
Thornley Colliery A Durham colliery founded partly on the winnings of a former bare-knuckle prizefighter turned MP, and the site of an 1841 explosion that killed eight boys and one man.	County Durham	1835 (sinking)–1970	Coal
Thornthwaite Mine Unusually for a Lake District lead mine, Thornthwaite kept working through the price slump of the 1870s-80s and was worked continuously from 1900 to 1920, reaching 85 fathoms by 1912 with a workforce of around 90.	Cumbria	1780s–around 1920-21	Lead, Zinc

Tilberthwaite Tilberthwaite's working life spans an almost absurd stretch of British mining history in one place — Elizabethan lead and copper prospectors in the 1500s, Victorian mining ambition driving a thousand-yard adit, and a slate quarry that was still being worked into the 21st century.	Cumbria	worked from the late 16th/early 17th century (Elizabethan)–1942 (copper)	Copper, Lead, Slate
Tillicoultry Colliery The Clackmannanshire drift mine that gave television its first live broadcast from underground, in 1952.	Clackmannanshire	1866 (first listed)–18 January 1957 (abandoned 1959)	Coal
Tilly Whim Caves 'Tilly Whim' most likely commemorates a quarryman named George Tilly and the wooden crane, the whim, that swung his finished stone down to waiting boats — the very same kind of crane that gave its name to the winding whims used at metal mines across Britain.	Dorset	18th century–around 1812	Freestone

Tincroft Mine Carn Brea and Tincroft together raised nearly half a million tons of copper in their combined working lives — output on a scale that puts them among the genuine giants of the Camborne-Redruth district, even though most of the mine's surface footprint today has simply been built over.	Cornwall	By the 1680s–1921 (South Tincroft)	Copper, Tin
Ting Tang Mine Carharrack mine in the West Clifford United sett, worked for tin before 1810 and copper through the mid-19th century.	Cornwall	By 1816–by 1870	Copper

Tir Edmund Colliery Its coal was shown at the Great Exhibition of 1851 and a Neath poet wrote verse about it, yet it closed in 1895 because the coal it was raising had gone poor.	Neath Port Talbot	By 1851–December 1895	Coal
Tir-y-Dail Colliery Built up to over 500 men in twenty-five years, then one of many Amman Valley pits whose end is tied to the defeat of the 1926 strike.	Carmarthenshire	1898–1927 (local histories)	Coal
Tirbach Colliery Its Big Vein could be seventy feet thick in one place and absent a few yards on, so the thick patches were worked over two or three times.	Neath Port Talbot	1899–1940 (training centre to 1961)	Coal

Tout Quarry A Portland stone quarry worked for two centuries and turned into a sculpture park in 1983.	Dorset	c. 1780–1982	Limestone

Tresavean Mine Before Michael Loam's man engine, reaching a working level at Tresavean meant climbing down — and, at the end of a shift, back up — as much as 1,728 feet of fixed ladders underground; the same journey on the new machine took a fraction of the effort, just by stepping from platform to platform as the rods rose and fell.	Cornwall	1737–1928	Copper, Tin, Arsenic
Treskerby Mine A productive Gwennap-area copper mine, part of the wider Consolidated/United Mines district.	Cornwall	By 1800–1922-27	Copper, Tin, Fluorspar

Tunstead Quarry The largest limestone quarry in the country, and the reason the Peak District National Park has a bite taken out of it.	Derbyshire	1929–Still active	Limestone
Turf Copper Mine Its 'ore' was peat: copper from the rock below had turned leaves, acorns and hazelnuts into metal, and the ash sold so well that one year cleared £20,000.	Gwynedd	Early 19th century–by mid-19th century	Copper
Turnavore Mine A 60-inch pumping engine is a serious piece of Cornish engineering -- and Turnavore's was thought valuable enough that when the shaft no longer needed it, the engine itself was moved next door rather than scrapped.	Cornwall	1837–1895	Tin, Copper
Tursdale Colliery A Bell Brothers pit of 1859 with its own coke ovens, merged into Bowburn in 1931, whose site became the Coal Board's national workshops until 1994.	County Durham	1854 (boring)–May 1966	Coal

Tyndrum Mines Tyndrum owes its lead mine to an accident of estate boundaries: Sir Robert Clifton, prospecting the Breadalbane estate he had leased in 1730, stumbled on the veins in 1741 without setting out to find them, and the mine his discovery started outlived him by nearly two centuries.

Tywarnhayle Mine Its 1906 flotation plant is described by Cornwall's own Historic Environment Record as the remains of 'the world's first commercial froth flotation plant' -- an extraordinary claim for a small, commercially unsuccessful Cornish revival, and one this record treats with real caution rather than repeating as fact.	Cornwall	1750–1864	Copper, Tin
