Coalbrookdale Colliery

Overview

The coal and ironstone workings that fed Abraham Darby's Coalbrookdale ironworks -- home of the first successfully sustained coke-fired blast furnace in Europe -- and the site of a fatal explosion in 1856 that killed eleven men and boys.

History

Coal had been worked at Coalbrookdale on a substantial scale since land here passed to John Brooke in 1572, feeding a succession of ironworking ventures; in 1709 Abraham Darby I took the lease of the Coalbrookdale furnace itself and, that same year, first successfully smelted iron using coke rather than charcoal, drawing on the colliery's own coal. Coalbrookdale is not, strictly, the site of the world's very first coke-fired blast furnace, but it was the first in Europe to operate successfully for more than a few years, and the coal and ironstone raised from the Coalbrookdale Company's own pits underpinned the ironworks' output for generations afterward -- including, from 1778, Abraham Darby III's casting of the parts for the world's first cast-iron bridge, opened at Ironbridge in 1780. The colliery's own working history was not without tragedy: on 3 July 1856 an explosion at the Old Coal Pit, then run by the partnership of Couttwell and Lewis, killed eleven men and boys, two of them rescuers who died going to the aid of the first victims. The subsequent Mines Inspector's report, by Mr Brough, found the explosion was caused by management's neglect of the colliery's own Special Rules for ventilation: safety lamps had not been locked, and there was no single main ventilation door to control the flow of air underground.

Workings

Worked coal and ironstone to supply the adjoining Coalbrookdale ironworks; the Old Coal Pit, the site of the 1856 explosion, relied on safety lamps and ventilation doors that an official inquiry found had been neglected.

Closure

No reliable single closure date has yet been located for the colliery specifically; the ironworks itself wound down blast-furnace production long before its 250th anniversary was marked in 1959 with the opening of a small museum on the site, later folded into the Ironbridge Gorge Museums.

What remains

No physical remains specific to the coal and ironstone workings themselves are recorded independently of the ironworks they fed; the Coalbrookdale Coalfield as a whole was largely built over as the town of Telford grew, and its last deep mine (Granville, unconnected to Coalbrookdale itself) closed in 1979. The valley's industrial landscape survives instead through the Ironbridge Gorge World Heritage Site, centred on the preserved 1709 blast furnace and Museum of Iron.

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.
