This is a partial glossary of common coal mining terms used in the United Kingdom. Some words were in use throughout the coalfields, some are historic and others are local to the different British coalfields.
- Adit: an underground level or tunnel to the surface for access or drainage.
- AfterdampDamps is the collective name given to all gases other than air found in coal mines in Great Britain. The chief pollutants are carbon dioxide and methane, known as blackdamp and firedamp respectively. : the mixture of gases that replaces atmospheric air after an explosion. Its composition depends on the conditions and circumstances of the explosion, the amount of firedamp present and whether it took place in the relatively fresh air entering the pit or at the end of the ventilation cycle, it typically contains carbon monoxide, carbon dioxide or both, as well as other gases including nitrogen, hydrogen and hydrogen sulphide.
- Bank: the area at the top of the shaft, also known as the pit bank or pit brow.
- Banksman: someone employed at the pit bank to dispatch the coals, and organise the workforce. The banksman is in charge of loading or unloading the cage, drawing full tubs from the cages and replacing them with empty ones.
- Bevin Boys: men conscripted to work in the coal mines during the Second World War in a scheme introduced by Ernest Bevin.
- Bell pit: a type of coal mine in which coal found close to the surface was extracted by sinking a shaft and removing coal from around it until the roof became unstable. It was then abandoned and left to subside.
- Blackdamp: a suffocating mixture of carbon dioxide and nitrogen produced after an explosion.
- Blower: an outburst of firedamp at pressure from fissures in the coal.
- Brattice: a strong canvas sheeting coated in tar to make it air-tight, used to make partitions to deflect air into particular areas of a mine or divide a shaft to improve ventilation and dilute flammable or noxious gases.
- Butterfly: a safety link or detaching hook above the cage attached to the winding rope to prevent the cage from being over wound. It was invented by Edward Ormerod
Edward Ormerod (2 May 1834 – 26 May 1894) was an English mining engineer and inventor who worked at Gibfield Colliery in Atherton, Lancashire where he devised and tested his safety device, the Ormerod safety link or detaching hook. .
- Cage The cage is the iron framework in which men and coal tubs are wound up and down the shaft. It could have one or more decks to increase its capacity.
- Cannel Cannel is coal that has a hard dense structure and is rich in hydrogen. It produces much gas and burns easily with a steady flame and for this reason is sometimes called “candle coal”.[a]from canwyl, a candle
- Check-weighman A check-weighman was appointed and paid by the miners to check the weight of the coal tubs at the pit top.
- Coal Coal is composed of vegetable matter which has been changed by chemical and physical processes over millions of years into a fossil fuel. It is a friable black rock that burns with a flame and smoke. It is principally made up of carbon (74 – 97%) and has a specific gravity of between 1.3 and 1.5. A cubic foot of solid coal weighs between 74 and 82 pounds. Seams of coal lie between strata of shales, clay and sandstone.
- DampDamps is the collective name given to all gases other than air found in coal mines in Great Britain. The chief pollutants are carbon dioxide and methane, known as blackdamp and firedamp respectively. is gas, derived from the German word dampf meaning vapour.

- Eye The eye or pit-eye is the mouth or top of the shaft.
- Face: the coal face is where coal is cut from the coal seam, either manually by hewers or mechanically by machine.
- Fall: a roof collapse in the underground workings. Immense falls follow explosions of firedamp.
- Fan: a centrifugal mechanical ventilator driven by steam power. Fans exhaust spent air out of the mine and fresh air is sucked in.
- FiredampDamps is the collective name given to all gases other than air found in coal mines in Great Britain. The chief pollutants are carbon dioxide and methane, known as blackdamp and firedamp respectively. : explosive, flammable gas consisting predominantly of methane (C2H4). It has a light specific gravity and is always found in the highest parts of the workings, cavities in the roof and goaves. It fires when mixed with four or five times its volume of air.
- Fireman: someone employed to examine the underground workings with a safety lamp to ascertain whether gas is present and by checking the doors, bratticing and stoppings maintains efficient ventilation. The first firemen, covered by sackcloth soaked in water, crawled into the area where gas was present on their bellies holding a long pole with a candle attached to explode the firedamp before the miners began their shift. They were sometimes called the “penitent” because of their ragged appearance.
- Furnace: used in the 19th century to ventilate the underground workings. The furnace was usually at the bottom of the upcast shaft, which acted as a chimney, creating airflow throughout the workings.
- Gannister Gannister is hard, compact, siliceous fireclay found in the floor of some coal seams which can be used to make firebricks.
- Gate A gate is a tunnel serving the coal face, the maingate is where fresh air enters and the tailgate is where spent air exits.
- Gin A gin or horse gin is a drum and framework with pulleys used to raise coal from shallow depths. A gin pit is a shallow pit shaft worked by a gin.
- Goaf The goaf, gove, gob, shut or waste is the void from which all the coal in a seam has been extracted and where the roof is allowed to collapse in a controlled manner.
- Gob fire A gob fire occurs by spontaneous combustion caused by the oxydisation of iron pyrites by moisture in the goaf. 
- Headframe The headframe, headstocks or headgear is the framework holding the winding wheel over the shaft.

- Outcrop The outcrop is where the coal seam is exposed at the surface.
- Pillar A pillar is a section of unworked coal supporting the roof. Unworked pillars of coal are left to prevent subsidence to surface features such as churches. The shaft pillar is left to prevent damage to the shafts from the workings.
- Pit A pit is the shaft, although it can refer to a colliery.
- Pit Brow Women Pit brow women Pit brow women were female surface labourers at British collieries. They worked at the coal screens on the pit brow (pit bank) at the shaft top until the 1960s. Their job was to pick stones and sort the coal after it was hauled to the surface. worked at the coal screens at the pit top up to the mid-1960s, mainly in the Lancashire and Cumberland coalfields.
- Props Props or pit props are timber or hydraulic supports holding up the roof.
- Putter A putter (Northumberland), hurrier (Yorkshire), waggoner or drawer (Lancashire) was the local term for the person who brought empty coal tubs up to the coal face and took loaded tubs to the pit bottom.
