20 mines beginning with Y, of 1950.
| Mine | Region | Worked | Commodities |
|---|---|---|---|
| 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 | No reliable opening date has yet been located.–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 |
| Yewthwaite Mine Worked in the shadow of Goldscope over the hill: when the neighbour struck lead in 1853, most of Yewthwaite's men simply went to it. |
Cumbria | 1849–1893 | Lead, Zinc |
| Yniscedwyn Colliery An Ystradgynlais anthracite mine whose flooded shaft forced a 1-in-3 drift, where nine men were sent runaway into the workings by a pulled stop block in 1892. |
Powys | 1872–22 March 1968 | Anthracite |
| 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 |
| Ynys Dafydd Colliery An explosion in the Nine-Feet seam killed twelve men and boys on 24 May 1856, one of the worst disasters recorded for this small Afan Valley pit. |
Neath Port Talbot | 1844 (possibly earlier)–1872 | Coal |
| Ynysamman Colliery A Brynamman anthracite level owned by the Ynysamman Colliery Company of Pontardawe, growing to 138 men by 1915–16. |
Carmarthenshire | 1909–1914 | 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 |
| Ynysfach Colliery A 19th-century mine sited near the Ynysfach Iron Works. |
Merthyr Tydfil | 19th century–No reliable closure date has yet been located. | Coal |

Neath Port Talbot | 1838–1927 | Coal |
| Ynysfeio Colliery The Troedyrhiw company's Rhondda Fawr steam-coal pits at Treherbert, deepened to the Gellideg at 335 yards in 1906 and 1,300 strong before Powell Duffryn shut them. |
Rhondda Cynon Taf | Level early 1850s; shaft 1856; Nos 3 and 4 sunk 1906–Production ceased c. 1930; pumping only by 1945 | Coal |

Rhondda Cynon Taf | No. 1 sunk from 1875; coal 1877–1968 | 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 |
| Ysguborwen Colliery Founded by Samuel Thomas, one of the pioneers of the Welsh coal trade, whose son David Alfred Thomas became Viscount Rhondda; its abandoned workings caused the fatal 1896 inrush at the neighbouring River Level Colliery. |
Rhondda Cynon Taf | c.1849–December 1895 (a level of the same name closed 1919) | Coal, Ironstone |
| Ystalyfera Colliery When the Coal Board closed it in 1957, its own divisional chairman said there was 'no rational excuse' for keeping the pit going. |
