Mine	Region	Worked	Commodities
Wyllie Colliery A whole village built and named for a colliery that only worked for 42 years.	Caerphilly	1926–1968	Coal
Wyndham Western Colliery Wyndham introduced South Wales's first miners' canteen offering a full hot meal service in 1942, and, in 1930, a system recording the colliery manager's own voice to warn men of hazards as their cage descended — modest, human-scaled innovations from a colliery whose Western half began with five men dying in a sinking explosion sixty years earlier.	Bridgend	Wyndham: sinking from 1865, shafts to Six-Feet seam completed 1868. Western: sunk 1873-75–January 1984	Coal
Wynnstay Colliery Struck by three separate fatal explosions in a single decade -- 1863, 1868 and 1873 -- killing thirty men and boys between them.	Wrexham	Opened in 1856, the property of the New British Iron Company.–Closed in 1927.	Coal
Yarner Copper Mine The mine's own engine house kept collapsing long after the copper ran out -- a 1978 rainstorm punched a fresh hole through it more than a century after the last ore was raised.	Devon	1857–1865	Copper
Yate Celestine Mines Ninety-five per cent of the world's celestine came out of these fields — and it was dug by farm labourers in the slack season	South Gloucestershire	1880s–1994	Celestine
Yesnaby Quarries A tsunami from the 1755 Lisbon earthquake reached this clifftop and nearly wrecked the quarry — and two centuries later the islanders themselves stopped a uranium mine here	Orkney	Millstone quarrying from an unknown early date–Quarrying declined after the Second World War	Freestone
Yew Craggs Quarry The other side of Honister Pass — green slate carried down by hand-sledge for a century, then by counterbalanced tramway.	Cumbria	Working by the early 18th century–Closeheads abandoned 1963	Slate
Yew Tree Colliery Site of the worst mining disaster in Tyldesley's history: a 25-death firedamp explosion in 1858, caused by a skipped safety inspection after the fireman overslept following a pay-rise celebration.	Lancashire	1845–19th century (exact closure date not established)	Coal
Ynisdavid Colliery Its seams were the Finery and the Sulphur: a colliery named by the copper and iron works it was sunk to feed.	Neath Port Talbot	By 1854–1872	Coal
Ynysarwed Colliery Already being worked under one owner or another for well over a century by the time it finally closed in 1955 — a genuinely old colliery whose exact opening date has been lost to an incomplete nineteenth-century record.	Neath Port Talbot	By 1823–December 1955	Coal
Yorkshire Main Colliery The colliery was renamed from 'Edlington Main' to 'Yorkshire Main' while still being sunk — a rebrand that stuck for the next seventy-four years.	South Yorkshire	Sinking began 1909; opened 1913–11 October 1985	Coal
Ystrad Einion Mine Small lead, copper and zinc mine in Cwm Einion, worked intermittently from the 18th century to 1903; retains a rare surviving underground waterwheel.	Ceredigion	18th century–1903	Copper, Lead, Silver, Zinc
Ystumtuen Mine Really a complex of several closely worked mines around the village it takes its name from, whose first industrial operator, the Company of Mine Adventurers, collapsed in 1709 amid accusations of fraudulent accounting.	Ceredigion	Working by 1698–Appears to have closed in 1882	Lead, Zinc
