Early mining The earliest reference to
coal mining in the Whitehaven area is in the time of Prior Langton (1256–1282) of St Bees Priory, concerning the coal mines at Arrowthwaite. St Bees Priory was dissolved in 1539, and the lands and mineral rights passed to secular owners. The first of these,
Sir Thomas Chaloner, granted leases of land in 1560 for digging coal, and in 1586 he granted St Bees School liberty "to take 40 loads of coal at his coal pits in the parish of St Bees for the use of the school". Such workings were small-scale and near the surface, using
adits and
bell pits. But the Lowther family later developed and dominated the coal industry in Whitehaven from the mid-17th century to the early 20th century.
The influence of the Lowthers Sir John Lowther, 2nd Baronet (1642–1706) significantly developed the coal industry and the trade with Ireland. He spent over £11,000 in expanding the Lowther holdings in the area, and considerably improved the drainage of his pits; thus allowing mining at greater depths. Consequently, a small (17-inch diameter cylinder)
Engine No. 5, built by Thomas Newcomen and
John Calley, was erected. It was so successful that in 1727 Lowther bought an additional pumping engine. With this proven method of pumping Lowther was able to exploit the coal measures under the sea by sinking a pit at Saltom on land below the cliffs south of the harbour, to a depth of 456 ft (138m). Work began early in 1730, and the pit was officially opened in May 1732 with great celebration. Carlisle Spedding had charge of the design and construction, and successfully sank only the second sub-sea pit in Britain. It was reported that "A shaft twelve foot by ten had been sunk seventy-seven fathoms" (141 metres) "(the deepest a pit had been sunk in any part of Europe) to a three-yard thick coal seam (the Main Band) in twenty-three months, using thirty barrels of gunpowder, and without any loss of life or limb by the workforce'. Saltom Pit ceased working coal in 1848, and is now a Scheduled Ancient Monument (SM 27801) and is the best known surviving example of an 18th-century colliery layout. Evidence of the shaft, horse gin, stable,
winding engine house, boiler house and chimney, cottages, cart roads and retaining walls, all survives. Coal excavated from Saltom Pit was raised by horse gin to the surface, then transported by tramway through a tunnel to Ravenhill Pit for lifting to the cliff top. Saltom Pit was used as a central pumping station, draining many of the other local mines via a drift driven in the 1790s, and continued in use long after it had ceased to work coal.
Technical innovation To counter the considerable danger of
methane gas explosion, Carlisle Spedding invented a forerunner to the
Davy Lamp, known as the Spedding Wheel or Steel Mill. This used the sparks generated by a flint against a rotating steel wheel to provide light, on the basis the sparks were not quite hot enough to ignite the gas. On occasions it caused explosions or fires but it was a major improvement over the naked flame. Haig was the last pit to operate in Whitehaven.
Temporary end of coal mining In 1983, a major geological fault was encountered at Haig pit which increased the difficulty of operation. This, combined with the political situation, and the
miners' strike in 1984–85, contributed to problems at the colliery. The workforce attempted to open a new face, but a decision had been taken to close, and after two years of recovery work, Haig finally ceased mining on 31 March 1986. Today there is no mining carried out in Whitehaven though there is a proposal to sink a
new mine out under the sea for coking coal. In November 2019 the UK government gave the green light for this mine to go ahead.
Preservation of Saltom pit In 2007, Copeland Council declared that it could no longer afford to maintain the remaining Saltom Pit buildings, and preserve them from damage by the sea. But after an online campaign by myWhitehaven.net, the council changed their mind. They teamed up with the
National Trust to try to save Saltom Pit, and obtained the necessary funding from various sources, including a 50% grant from the
European Union. On Monday 8 December 2007, Saltom Pit was reopened as an historic monument. The pit buildings have been conserved and are now part of the 'Whitehaven Coast' project, a scheme to regenerate the coastal area of Whitehaven. ==Climate==
