By 1966 there were seven spoil heaps, comprising approximately 2.6 million cu yd (2.0 million m 3) of waste. [8] [9] [a] Tips 4 and 5 were conical mounds at the apex of the slope, although Tip 4 was misshapen from an earlier slip; the remaining five were lower down; all were directly above the village. Tip 7 was the only one being used in 1966.
Richard Llewellyn's novel How Green Was My Valley (1939) describes the social and environmental effects of coal mining in Wales at the turn of the 20th century. The local mine's spoil tip, which he calls a slag heap, is the central figure of devastation. Eventually the pile overtakes the entire valley and crushes Huw Morgan's house:
In the 1966 Aberfan disaster in Wales, a colliery spoil tip collapsed, engulfing a school and killing 116 children and 28 adults. Other accidents involving coal waste include the Martin County coal slurry spill (US, 2000), the Kingston Fossil Plant coal fly ash slurry spill (US, 2008), and the Obed Mountain coal mine spill (Canada, 2013).

She was found alive by a cyclist fifty minutes later; had this cyclist not come across her and called an ambulance, she likely ...
The first step in the investigation of archaeometallurgical slag is the identification and macro-analysis of slag in the field. Physical properties of slag such as shape, colour, porosity and even smell are used to make a primary classification to ensure representative samples from slag heaps are obtained for future micro-analysis.
