A brattice is a partition used in mining. It is built between columns of a sub-surface mine to direct air for ventilation. [1] Where the mine is sunk at the base of a single shaft, the shaft is divided into two parts by a wooden or metal brattice. Air is delivered down one side of the shaft and exhausted upwards through the other. [2]
Depending on the type of mine and how the operation is run, brattices can be permanent (concrete or wood) or temporary (cloth). Temporary installations are also called curtains.
Early collieries sometimes only had one pit which was divided by a brattice. A furnace was kept burning within the pit and the hot air rose up the one side of the brattice (the upcast side) drawing cold air down the other (the downcast side). One such pit was Hartley pit. In 1862 the beam of the pumping engine failed and brought down part of the lining resulting in the pit being blocked. All the men trapped underground died from carbon monoxide poisoning as a consequence of the lack of ventilation. As a result, an Act of Parliament was passed later in the year requiring all collieries to have at least two shafts. Rather than bratticing one shaft, it was more convenient to use one shaft as the upcast pit and the other as the downcast pit. Underground however, brattices remained vitally important for directing the current of air throughout the whole of the colliery. [1]
In an 1868 article titled "Coal" in the All the Year Round periodical, the author describes the workings of a ventilation shaft in a mine and a brattice: [3]
Changes from gusty windiness to tropical heat are sudden. Lifting a coarse canvas curtain, and passing under it, takes us at once from Siberia to the torrid zone. In the first we are among vast currents of air coming fresh and cold into the pit; in the second we stand amid hot and exhausted air which is being forced outwards by the furnace. Canvas or "brattice-work" divides the two, and the vast labyrinthian passages along which coal has been or is being worked are cold or hot according to the turn the ventilation has been made to take.

Brattice, from the French bretèche, originally referred to part of a castle. This was a small wooden structure, sometimes temporary, that projected out beyond the main part of a castle wall, so as to give flanking fire along that wall whilst still offering some degree of protection. See hoarding.
The Blantyre mining disaster, which happened on the morning of 22 October 1877, in Blantyre, Scotland, was Scotland's worst ever mining accident. Pits No. 2 and No. 3 of William Dixon's Blantyre Colliery were the site of an explosion which killed 207 miners, possibly more, with the youngest being a boy of 11. It was known that firedamp was present in the pit and it is likely that this was ignited by a naked flame. The accident left 92 widows and 250 fatherless children.
Easington Colliery is a town in County Durham, England, known for a history of coal mining. It is situated to the north of Horden, a short distance to the east of Easington Village. The town suffered a significant mining accident on 29 May 1951, when an explosion in the mine resulted in the deaths of 83 men.
The Hartley Colliery disaster was a coal mining accident in Northumberland, England, that occurred on 16 January 1862 and resulted in the deaths of 204 men and children. The beam of the pit's pumping engine broke and fell down the shaft, trapping the men below. The disaster prompted a change in British law that required all collieries to have at least two independent means of escape.
The Oaks explosion, which happened at a coal mine in West Riding of Yorkshire on 12 December 1866, remains the worst mining disaster in England. A series of explosions caused by firedamp ripped through the underground workings at the Oaks Colliery at Hoyle Mill near Stairfoot in Barnsley killing 361 miners and rescuers. It was the worst mining disaster in the United Kingdom until the 1913 Senghenydd explosion in Wales.
The Felling Colliery in Britain, suffered four disasters in the 19th century, in 1812, 1813, 1821 and 1847. By far the worst of the four was the 1812 disaster which claimed 91 lives on 25 May 1812. The loss of life in the 1812 disaster was one of the motivators for the development of miners' safety lamps such as the Geordie lamp and the Davy lamp.
New Hartley is a small village in South East Northumberland, England, adjacent to Hartley, Seaton Delaval and Seaton Sluice. The village is just off the A190 road about 6 miles north of Tynemouth and 4 miles south of Blyth.
Clifton Hall Colliery was one of two coal mines in Clifton on the Manchester Coalfield, historically in Lancashire which was incorporated into the City of Salford in Greater Manchester, England in 1974. Clifton Hall was notorious for an explosion in 1885 which killed around 178 men and boys.
Pleasley Colliery is a former English coal mine. It is located to the north-west of Pleasley village, which sits above the north bank of the River Meden on the Nottinghamshire/Derbyshire border. It lies 3 miles (4.8 km) north of Mansfield and 9 miles (14.5 km) south of Chesterfield. From the south it commands a prominent position on the skyline, although less so now than when the winders were in operation and both chimney stacks were in place. The colliery is situated at about 500 ft (152m) above sea level and is aligned on a NE–SW axis following the trend of the river valley at this point.
Chatterley Whitfield Colliery is a disused coal mine on the outskirts of Chell, Staffordshire in Stoke on Trent, England. It was the largest mine working the North Staffordshire Coalfield and was the first colliery in the UK to produce one million tons of saleable coal in a year.
The West Stanley Pit disasters refers to two explosions at the West Stanley colliery. West Stanley colliery was a coal mine near Stanley, with the mine opening in 1832 and closing in 1936. Over the years several seams were worked through four shafts: Kettledrum pit, Lamp pit, Mary pit and New pit. In 1882 an underground explosion killed 13 men and in 1909 another explosion killed 168 men.
Gresford Colliery was a coal mine located a mile from the North Wales village of Gresford, near Wrexham.
The Avondale Mine disaster was a massive fire at the Avondale Colliery near Plymouth Township, Pennsylvania, on September 6, 1869. It caused the death of 110 workers. It started when the wooden lining of the mine shaft caught fire and ignited the coal breaker built directly overhead. The shaft was the only entrance and exit to the mine, and the fire trapped and suffocated 108 of the workers. It was the greatest mine disaster to that point in American history.
Parsonage Colliery was a coal mine operating on the Lancashire Coalfield in Leigh, then in the historic county of Lancashire, England. The colliery, close to the centre of Leigh and the Bolton and Leigh Railway was sunk between 1913 and 1920 by the Wigan Coal and Iron Company and the first coal was wound to the surface in 1921. For many years its shafts to the Arley mine were the deepest in the country. The pit was close to the town centre and large pillars of coal were left under the parish church and the town's large cotton mills.
Pendlebury Colliery, usually called Wheatsheaf Colliery after the adjacent public house, was a coal mine operating on the Manchester Coalfield after 1846 in Pendlebury near Manchester, then in the historic county of Lancashire, England.
Mosley Common Colliery was a coal mine originally owned by the Bridgewater Trustees operating on the Manchester Coalfield after 1866 in Mosley Common, Greater Manchester, then in the historic county of Lancashire, England. The colliery eventually had five shafts and became the largest colliery on the Lancashire Coalfield with access to around 270 million tons of coal under the Permian rocks to the south.
Bradford Colliery was a coal mine in Bradford, Manchester, England. Although part of the Manchester Coalfield, the seams of the Bradford Coalfield correspond more closely to those of the Oldham Coalfield. The Bradford Coalfield is crossed by a number of fault lines, principally the Bradford Fault, which was reactivated by mining activity in the mid-1960s.
Great Western Mine, also known as Hetty Pit, was a coal mine, at Hopkinstown, near Pontypridd, Glamorgan in South Wales.
This is a partial glossary of coal mining terminology commonly used in the coalfields of the United Kingdom. Some words were in use throughout the coalfields, some are historic and some are local to the different British coalfields.
The Peckfield pit disaster was a mining accident at the Peckfield Colliery in Micklefield, West Yorkshire, England, which occurred on Thursday 30 April 1896, killing 63 men and boys out of 105 who were in the pit, plus 19 out of 23 pit ponies.
The Lundhill Colliery explosion was a coal mining accident which took place on 19 February 1857 in Wombwell, Yorkshire, UK in which 189 men and boys aged between 10 and 59 died. It is one of the biggest industrial disasters in the country's history and it was caused by a firedamp explosion. It was the first disaster to appear on the front page of the Illustrated London News.
