The Coal Authority now term all underground mines "Deep Mines" so there are currently eleven deep mines in existence (mostly 2014 data, some 2013 data):
Three shaft mines:
Kellingsley (UK Coal) employing c.700 and producing c.1.4mt pa; to close by the end of 2015.
Thoresby (UK Coal) employing c.600 and producing c.1.2mt pa; to close by the end of 2015.
Hatfield (Hatfield Colliery Partnership) employing 500 and producing c.1.0mt pa; to close by summer 2016.
Two medium size drift mines:
Aberpergwm (Energybuild Ltd, a subsidiary of Walter Energy Inc of USA) employing 60-odd on development during which work around 01.mt pa or somewhat less is produced. Until the end of 2013 it employed around 300.
Unity (Unity Mine Ltd) mothballed and seeking a purchaser.
One 'large' small mine:
Eckington (European Coal Products) employing around 20 and producing around 20kt pa. Its planning consent expires in January 2023 which coincides with the coal within its licence also running out.
Five small mines (some of which used to be termed “micro mines” by the Coal Authority):
Ayle (Ayle Colliery Co) - anyone got up to date information?
Hill Top (Grimebridge Colliery Co Ltd) – produced 3kt in 2011 suggesting around 3 or 4 employed. It has to close no later than August 2018 which is when its planning consent expires.
Monument (Ray Ashly, Richard Daniels & Neil Jones) - anyone got up to date information?
Dan y Graig No.4 (Three D's Mining Ltd) – coaling as of 2013 and 2014; anyone got up to date information?
Nant Hir No.2 – reopening as of 2014 and as of present; anyone know the name of the company that owns it?
To these can be added:
Crofton (New Crofton Co-Operative Colliery Co Ltd) – secured planning permission 2014 and is now seeking finance to start developing; its proposals speak of up to 50 jobs.
In 2014 the UK produced 11.5mt (3.7mt deep mined and 7.8mt from “surface mines”) and imported 40.7mt (46% from Russia, 27% from Columbia, 23% from USA, 2% from the EU and 2% from other countries).
In 2014, coal usage was divided between: power stations 38.4mt, coke ovens and blast furnaces 6.4mt, domestic 0.6mt; patent fuel (also mostly domestic) 0.3mt, other users 1.6mt.
In 2014 the energy mix for electricity generation was: gas 30%, coal 29% nuclear 19% and renewable 19%. Renewables was made up of: bioenergy 6.8%, onshore wind 5.5%, offshore wind 4.0%, hydro 1.8%, solar 1.2%.
At the end of the year coal stocks, mostly held at power stations, totalled 18mt.
Some of the percentages will not add to exactly 100% due to rounding.
https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/415987/coal.pdf UK preserved railways ran 1.3m passenger train miles in 2014 *. If - and this is a wild guess - average coal consumption is 1cwt per mile (allowing for coal used firing up, standing at stations, etc), then UK preserved railways use 65kt pa. The actual figure might be half this, twice this or four times this but either way its a fraction of 1% of total UK consumption.
