Pochin Colliery is location near Tredegar in the Sirhowy Valley. The colliery was operated and sunk c. 1876, by the Tredegar Iron Company and was named after the daughter of one of their directors, Henry Davis Pochin. The first coal was raised in 1881. At this time the colliery consisted of the North and South Pits (shafts). By 1888 the colliery was working the Big Vein and Yard Seams (prime coking coals). In 1897 a washery was installed to reduce product ash contents and to increase product marketability. By 1935 Pochin was the largest of TIC's South Wales collieries. The colliery closed in 1964. The site is now largely landscaped.
