Gurnos Colliery Explosion, 1909
| Date | 17 December 1909 |
|---|---|
| Mine | Gurnos Colliery |
| Region | Powys |
| Primary type | Explosion |
| Associated types | Gas / Asphyxiation |
| Fatalities | 2 (William Belton, 24, collier (left a widow and two children); John Maloney (or Moloney), 24, repairer, single.) |
| Injuries | Three seriously burnt, including the fireman David Enoch Jones and Morgan Mainwaring; Thomas Lewis Jones, 18, slightly burnt. |
| Context | During active mining |
A shot fired at the face just before 5 am ignited gas and engulfed the men nearby in flames, fatally burning the collier who had prepared it and burning the fireman. A repairer working further off, unhurt by the blast, set off towards the return airway rather than out of the mine and was later found a few yards away, overcome by gas.
Cause
A shotfiring accident: the shot ignited gas at the face.
Contributing factors
Unknown; the sources give no finding on the gas or the shotfiring practice.
What happened
William Belton prepared a shot and the fireman, David Enoch Jones, fired it; at once the men near the face were enveloped in flames. Belton, stripped to the waist, was burnt from head to foot; the fireman saved his face and hands by throwing himself flat. Further along the heading the repairer John Maloney and an 18-year-old, Thomas Lewis Jones, felt the blast. Jones asked Maloney to come out with him, but Maloney went the other way, towards the return airway.
Rescue & recovery
Jones found his own way to the surface and, without treatment for his burns, went to Glantawe Road for help. Maloney's body was found only a few yards from where they had parted. Belton was carried home on a stretcher; the fireman and Morgan Mainwaring walked home despite serious burns.
Investigation & inquiry
Unknown; no inquest report was found.
Legal & regulatory aftermath
None recorded.
Changes to practice & legislation
None recorded.
Memorials & commemoration
