• Bryngwiog Mine inrush, 1862
  February 1862 · Flooding / Inundation · Flintshire · 16 fatalities
  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.
• Wheal Owles flooding disaster
  10 January 1893 · Flooding / Inundation · Cornwall · 20 fatalities
  Miners broke through into the flooded, long-abandoned workings of Wheal Drea, trapping and drowning twenty men and boys underground.
• East Pool Mine shaft collapse
  1921 · Collapse / Roof Fall · Cornwall · 0 fatalities
  A large underground rockfall destroyed both of East Pool's winding shafts and flooded the mine; no deaths were reported, but the mine had to sink an entirely new shaft to survive.
• Keppel Cove dam burst, 1927
  night of 28–29 October 1927 · Flooding / Inundation · Cumbria
  After a night of exceptional rainfall and gale-force winds, the earth dam supplying Greenside Mine's hydro-electric power at Keppel Cove was overtopped and burst, sending a flood down into Glenridding village that wrecked shops, bridges and a hotel — four hotel staff were rescued from a flooding basement.
• Wheal Jane acid mine water discharge, 1992
  13 January 1992 · Flooding / Inundation · Cornwall
  An estimated 50,000 m³ of acidic mine water burst from the flooding, abandoned Wheal Jane workings and turned the Carnon River and Fal estuary ochre-yellow — one of the most notorious mine-water pollution incidents in British history, and one still being actively treated more than three decades later.
