Bersham Colliery

Overview

A North Wales colliery that survived two fatal 19th- and early 20th-century explosions to become, alongside Point of Ayr, one of the region's last two working pits.

History

The Bersham Coal Company sank a colliery called Glan-yr-afon on this site in 1864, but it lay idle for six years before Messrs Barnes and Company reopened it in 1871, deepening the shafts to reach the Main Coal seams; production of that seam began in 1874. On 5 September 1880, a major underground explosion killed nine men, including colliery manager William Patterson. A second explosion, on 3 August 1909, was caused when a shot fired at the far end of the No.2 West Level ignited a pocket of firedamp; it killed eight men — firemen Joseph Matthias, Edward Owen, John Jones and James Roberts, colliers Thomas Evans and Evan Parry, hacker Robert Lloyd, and Henry Valentine, who was brought out alive but died a few days later. A new headgear was installed at No.2 Shaft in 1930 after fire destroyed the original timber structure. At its peak the wider Wrexham coalfield, of which Bersham was part, supported 38 separate collieries producing over 2.5 million tonnes of coal a year for local brickworks and steelworks including Brymbo and Shotton. Following the 1974 miners' strike, Bersham became one of only two remaining North Wales collieries, alongside Point of Ayr, and it finally closed in December 1986 with the loss of 480 jobs.

Geology

Bersham worked coal seams of the Denbighshire (Wrexham) coalfield, reaching the Main Coal seam at depth from 1874.

Workings

Coal was raised via No.2 Shaft, reaching 1,269 feet (387m) deep, served from 1930 by a replacement steel headgear installed after fire destroyed the original timber structure.

Closure

Bersham closed in December 1986 with the loss of 480 jobs, having become, alongside Point of Ayr, one of only two working collieries left in North Wales after 1974.

What remains

The No.2 headgear, with its wheel, and the winding engine house survive and are preserved by volunteers from the North Wales Miners Association Trust.

The No.2 shaft headgear and its winding engine house, both preserved as a visitor attraction.

Abandoned workings can be dangerous — unstable ground, uncapped shafts, flooding and bad air are common even where a site looks safe from the surface. This entry describes history and general location only; it is not an access guide.
