Context During active mining
Status Researched

A heavy fall of rock at Celynen South Colliery's No. 3 pit trapped collier Joseph Absalom and his young assistant Alfred Phillips at the coal face. Despite a rescue effort lasting up to 26 hours, during which the trapped men could still be heard, both died before they could be freed.

Cause

A sudden 'squeeze' acting on a weak section of roof between a geological 'grime' and a fault brought down several hundred tons of rock and earth at the working face.

What happened

Absalom and Phillips were fastened and imprisoned by the fall at the coal face. Rescuers could hear the two men for around 12 hours as they worked to reach them; Phillips died after about 16-18 hours, and Absalom, found sitting with a large stone resting on him, survived roughly 26 hours before a further fall during the rescue proved fatal.

Rescue & recovery

Rescuers worked continuously to free the two men, administering stimulants and attempting to clear the fall carefully so as not to bring down more roof; a second, smaller fall during the effort killed Absalom shortly before he could be reached.

Investigation & inquiry

HM Inspector of Mines found no blame attached to anyone for the accident, and praised the “efficiency and courage displayed by all concerned, from the manager downwards,” in the rescue attempt.
