Cause

A second fall of roof, about ten trams in size, came down without warning while an earlier fall was being cleared, discharging three pairs of timber.

What happened

The overman, Penry Davies, had set Gough, Cox and Davies to clear a fall at the end of the double parting, with the fireman David Thomas supervising; two pairs of timber had come out with the first fall. Gough and Thomas had examined the roof and thought it safe. A haulier, Joseph Evans, had taken ten trams of rubbish away and about two trams remained when, at about 10.25 in the morning, a second fall of about ten trams came on the pit side and knocked out three more pairs of timber. Davies was killed outright; Thomas was badly hurt and died; Gough and Cox were injured. Both dead men were pinned under the fall for a short time.

Investigation & inquiry

The coroner, R. J. Rhys, held the inquest at the Cwmaman Institute; the manager, William Jones, produced a plan of the workings, and the miners' agent and the firemen's association were represented. The jury returned a verdict of accidental death.
