Cause
Hidden corrosion in a braided steel flat winding rope, where it ran over the headframe sheave.
What happened
In December 1884 sinkers at Harris's Navigation Colliery, Treharris, then among the deepest pits in Wales at around 770 yards, were working in one of the shafts to improve it, using a bowk on a braided steel flat rope while the cage was out of use. In the early hours of Friday 12 December five men had come up for their food and were being lowered again when, a few dozen yards down, the rope broke. The bowk and four of the men fell to the bottom, some 700 yards below.
The fifth man, John Dodds, was steadying the bowk on a guide rope and held on. Wrapping his coat round the wire, he let himself down hand over hand for hundreds of yards until he became tangled in the signal wire, which the falling bowk had torn loose, and could go neither up nor down. He hung there for hours before a party reached him through the other shaft. The rope, less than a year old, was found to have hidden corrosion beneath its coating of tar where it ran over the headframe sheave. The four dead were sinkers, named by Welsh Coal Mines as Francis Wright, Evan Jones, Evan Hughes and Thomas Sheen.
Rescue & recovery
The survivor, John Dodds, slid down a guide rope until trapped by the signal wire and was reached hours later through the other shaft; the bodies were recovered over the following day.
Investigation & inquiry
The inquest was adjourned so that an expert sent by the Home Office could test the rope.
