Cwmneol Colliery

Overview

Morris's pit at Cwmaman, near Aberdare, sunk in 1848 as the first pit in the Cwmaman area and bought by Powell Duffryn in 1866. In 1855 eight men died when their cage overshot the headgear and fell 240 yards, and in 1930 three more were killed when a cage rope broke; it closed in 1948.

History

Cwmneol Colliery, known locally as Morris's pit, was sunk in 1848 by Martin Morrison and John and Charles Carr between Aberaman and Fforchaman collieries near Cwmaman, the first pit in the Cwmaman area; a second, upcast shaft, the North or 'Lanky' pit, followed by 1850. The accounts differ on the seam first reached: the Seven Feet at 359 yards by one, the Four Feet by another. Ventilation was by furnace and winding by water balance until 1855. On 28 November 1855 a cage carrying eight men up the shaft overshot the bank, crashed into the headgear and broke the rope, and all eight fell 240 yards to their deaths; the inquest found a casual system of signalling between shaft and engine house, and the young engine driver, Solomon Lloyd, was tried for manslaughter and acquitted. Owned by Carr and Morrison in 1858, D. Prothero and Company in 1860 and the United Merthyr Collieries Company in 1865, Cwmneol was bought in 1866 by Sir George Elliot for the new Powell Duffryn Steam Coal Company. Its shafts were sunk to over 1,040 feet; it stood idle from 1893 to 1898 while they were deepened and the plant renewed, then worked the Nine Feet, Red and Bute seams, the Seven Feet proving split and unworkable, employing up to 850 men around 1919. Three men were killed on 17 August 1930 when a cage rope broke and the cage fell on them at the pit bottom. Under the National Coal Board from 1947, Cwmneol was closed on 31 January 1948 when its coal was exhausted.

Geology

Steam coal seams of the South Wales coalfield: first the Seven Feet or Four Feet, later the Nine Feet, Red and Bute, and by the 1940s the Two Feet Nine, Yard and Four Feet; the Seven Feet proved split by thick stone bands and unworkable.

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

Workings

Two shafts: the South pit, and the North or 'Lanky' upcast pit added by 1850. Wound by water balance until 1855; the shafts were later deepened to 1,041 and 1,078 feet, with a Fraser and Chalmers compound winding engine, compressed-air and fan engines and electric underground haulages by 1914.

Closure

Closed by the National Coal Board on 31 January 1948 because its coal reserves were exhausted. It had also stood idle from 1893 to 1898 while the shafts were deepened, and from June 1928 to February 1929 in the trade depression.

What's uncertain

Points where sources disagree or the record could not be settled; both accounts are kept. All open questions in the archive.

• The Cwmneol South pit opened to the Seven Feet seam at 359 yards in 1848, sunk by Messrs Carr and Morrison, with the North or 'Lanky' upcast pit added by 1850. (disputed) ¹
• Cwmneol was sunk to the Four Feet seam by Martin Morrison and John and Charles Carr in 1848, the first pit in the Cwmaman area, and used water-balance winding until 1855. (disputed) ²
• In 1865 the Aman Aberdare Coal Co. Ltd became the owners, and by 1868 the colliery was in the hands of Powell Duffryn; production ceased in 1893 to deepen the shafts and restarted in 1898. (disputed) ¹
