Sixteen men drowned when Bryngwiog Mine, on Halkyn Mountain, broke into the flooded old workings of the abandoned Hendre Mine and filled with water within minutes — one of the worst disasters in the district's lead-mining history.
Cause
Seventeen men working underground broke through into the old, abandoned and flooded workings of the nearby Hendre Mine, releasing a rapid inrush of water into Bryngwiog.
Contributing factors
The Hendre Mine's old workings were not adequately known or marked before Bryngwiog's own workings were driven close enough to hole into them.
What happened
Bryngwiog Mine, at Moel-y-Crio on Halkyn Mountain, was being developed for lead when its workings broke through a wall into the flooded, abandoned workings of the old Hendre Mine. Seventeen men were underground at the time; water flooded the mine within minutes. One man, Edwin Powell, managed to reach the shaft and catch a rope, and was hauled out barely conscious. The other sixteen drowned.
Rescue & recovery
The mine's pumping engine worked continuously to clear the water. The first body recovered, Edward Goodwin, was brought up the day after the flood; further bodies were recovered over the following days, with most retrieved within the week. Thousands of people are reported to have gathered at the mine while recovery was under way.
Investigation & inquiry
A coroner's inquest was held at the Royal Oak, chaired by Peter Parry. Mines inspector Peter Higson examined the workings and testified that water had broken through into the 132-yard level from the old, deeper Hendre workings. The jury returned a verdict of accidental death.
Legal & regulatory aftermath
Public meetings were held in Mold, Rhyl and Holywell to raise relief funds for the bereaved families.
