Overview
A long-lived Dowlais-feeder level whose haulage rope, by the 1850s, ran 3,000 yards to pull up to 35 trams at a time. It worked successive seams for over sixty years before its final abandonment in 1924.
History
Brewhouse Colliery was worked to feed the Dowlais Ironworks with coal, clay and iron. As early as the 1850s it had a haulage rope 3,000 yards long, used to pull 30 to 35 trams at a time. Over the following decades it worked and abandoned a succession of seams: the Elled in 1859, the Upper Four-Feet in 1893, the Brass Vein in November 1901, the Lower Four-Feet in 1908 (and the top part of that same seam in 1917), the Six-Feet in 1914, and the Seven-Feet, Red and Nine-Feet seams all in 1917. The colliery itself was finally abandoned in May 1924. The Dowlais Ironworks it fed had been founded in 1759 and grew, under John Josiah Guest, into one of the largest ironworks in the world, running 18 blast furnaces and employing 7,300 people at its 1845 peak. Guest, Keen and Nettlefolds was formed from the works in 1899–1902, and the main Dowlais plant continued production until 1936.
Geology
Worked the Elled, Upper and Lower Four-Feet, Brass Vein, Six-Feet, Seven-Feet, Red and Nine-Feet seams of the South Wales Coalfield in succession, from 1859 to 1917.
Workings
A drift/level fed by a 3,000-yard haulage rope pulling 30–35 trams at a time, working the Elled, Upper and Lower Four-Feet, Brass Vein, Six-Feet, Seven-Feet, Red and Nine-Feet seams in succession.
Closure
Finally abandoned in May 1924, after more than sixty years supplying the Dowlais Ironworks.
