"Where was ""the Aberfan Disaster"" where the collapse of a colliery spoil-tip in 1966 killed 144 people, including 116 children?"
Spoil tip With spoil tips there is a danger of landslip. The best-known example is the Aberfan disaster in Wales of 1966, killing 144 (most of them children). Water from heavy rainfall had built up inside the tip, weakening the structure, until it suddenly collapsed onto the school below. In February 2013, a spoil tip was the cause of a landslip which caused the temporary closure of the Scunthorpe to Doncaster railway line in England. Several techniques of re-utilising the spoil tips exist, usually including either geotechnics or recycling. Most commonly, old spoil tips are partially revegetated to provide valuable green spaces

A period of heavy rain led to a build-up of water within the tip which caused it to suddenly slide downhill as a slurry, killing 116 children and 28 adults as it engulfed the local junior school and other buildings. The tip was the responsibility of the National Coal Board (NCB), and the subsequent inquiry
