A ventilation-system fire at Bwllfa Colliery filled an underground drift with smoke during a shift change on 27 December 1867, killing five of the eleven men working there.
| Date | 27 December 1867 |
|---|---|
| Mine | Bwllfa Dare Colliery |
| Region | Rhondda Cynon Taf |
| Primary type | Fire |
| Associated types | Gas / Asphyxiation |
| Fatalities | 5 (Richard Lloyd (44), Thomas Wood (28), Thomas Howell (28), Benjamin Thomas (55) and John Daniel (50) died; four were found dead in the heading and one of seven rescued men subsequently died of his injuries.) |
| Context | During active mining |
Cause
A wire rope being lowered down the shaft in a wooden box caught fire from furnace sparks, and the fire spread to the ventilation air tube itself; friction from the rope was suspected as a possible ignition source, though the exact cause was never conclusively established.
What happened
The fire broke out in the ventilation system while eleven men were working in a drift during a shift change. Smoke from the burning air tubes filled the heading and compromised the air supply. Volunteers rescued seven miners in a weakened state, one of whom later died of his injuries; four more were found dead in the heading itself, bringing the total to five.
Rescue & recovery
Seven men were rescued from the smoke-filled heading by volunteers, though in a weakened state; one subsequently died.
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 exact ignition source was never conclusively established, though friction from a wire rope being lowered past the burning air tube was suspected. (uncertain)
- A second source (welshcoalmines.co.uk) names the five victims slightly differently -- Benjamin Lloyd (46), Thomas Wood (35), Benjamin Thomas (57), Thomas Owen (24) and John Daniel (50) -- against the NMRS record's Richard Lloyd (44), Thomas Wood (28), Thomas Howell (28), Benjamin Thomas (55) and John Daniel (50); both are kept on record rather than silently reconciled. (disputed)
