Overview

A group of anthracite pits at Thomas Chapel, Begelly, worked from 1784 at the head of the Saundersfoot Railway. Six men drowned in an inrush in 1838, and the 1842 Royal Commission found young girls hauling coal underground; the colliery was finally abandoned in 1867.

History

Thomas Chapel Colliery, in Begelly parish near Kilgetty, was the name for a group of anthracite workings in the eastern Pembrokeshire coalfield, confined between the Reynalton fault to the west and the Bramble Hill fault to the east, with a mineral take of 1,000 acres. Welsh Coal Mines dates its first pits, the Old Wheel Pit (165 feet) and the Hay Pit, to 1784, followed by the Stump Park, Hackett and Air pits in the 1790s and the Horse Wheel, Pond Landing and Pond Engine pits in 1836-40, working the Lower Level and Kilgetty seams; Coflein says only that it had opened by 1843. A four-foot-gauge tramway, part of the Saundersfoot Railway, reached it in the 1830s, and its anthracite was shipped from Saundersfoot to south-east England for the brewing trade. On 16 June 1838 the miners cut into old water-filled workings and six men of Begelly drowned; it took pumping night and day at two pits, helped by a steam engine at a third, before the bodies could be reached. William Brace, named as the owner in one account and the manager in another, was charged with manslaughter on the prosecution of one victim's father, but the case went no further than the grand jury at Haverfordwest in March 1839. The Royal Commission of 1842 found children as young as seven working there as trammers, among them girls of eleven dragging loads along roadways under three feet high. It was held in 1842 by Thomas Stokes and Company, or by Morgan Hughes and Company, and was bought in 1851 by the Pembrokeshire Iron and Coal Company; two more colliers drowned in an inrush in July 1854. Abandoned as 'Thomas Chapel or New Hayes' in 1857, it was listed again from 1858 and finally abandoned in 1867, as New Hayes; a company registered in 1875 to acquire it offered it for auction in 1878.

Geology

Anthracite of the Pembrokeshire coalfield: the Lower Level and Kilgetty seams, in ground bounded by the Reynalton and Bramble Hill faults.

Geological setting: Sedimentary Beds and Seams (well documented example)

Workings

Several shallow shafts: the Old Wheel Pit (165 ft) and Hay Pit (114 ft) of 1784, Stump Park (1790, 162 ft), Hackett (1794, 174 ft) and Air (1799, 108 ft) pits to the Lower Level seam, the Horse Wheel (60 ft), Pond Landing (96 ft) and Pond Engine (144 ft) pits of 1836-40 to the Kilgetty seam, and the 10-foot New Hayes Pit to the Kilgetty seam at 468 ft. Windlasses, skips and trams underground; the Saundersfoot Railway ran from the pit mouth.

Closure

Abandoned in 1857 as 'Thomas Chapel or New Hayes', listed again from 1858 and finally abandoned in 1867 as New Hayes (Welsh Coal Mines). Another account on the same page has it worked by the Pembrokeshire Iron Company in 1865, in a list of 1869 and closed before 1880. The Saundersfoot and Tenby Collieries Company, registered in 1875 to acquire it, advertised it for auction on 17 May 1878.

What remains

A ruined, ivy-covered stone building stands in woodland on the colliery site (photographed in 2009).

The 1889 Ordnance Survey map shows tips, an old engine house and an old shaft, and the 1907 map an old coal shaft; a ruined stone building survives among trees.
