Cause

The haulage rope snapped and the journey ran away down the incline.

Contributing factors

The haulage engine driver had been signalled to stop and, restarting, had to use full steam, at which the rope parted. The inquest jury put the accident down to a deficient rope and an error of judgment by the ropeman, who, the foreman of the jury said, had put on too many trucks.

What happened

The two men were walking up the incline at the end of the shift and had probably stopped the journey so that they could ride on it to the top.

Investigation & inquiry

The adjourned inquest was held at Treorchy Workmen's Institute before the district coroner, R. J. Rhys, with Colonel Pearse representing the Home Office and the Miners' Federation also represented. The jury returned a verdict of accidental death and added a rider that it was due to a deficient rope being in use and an error of judgment on the part of the ropeman.
