The 26 July 2016 landslide at Fushun west pit in China<\/h4>\n

On 26 July 2016 a large landslide occurred in a highwall at a large coal mine<\/a> in Fushun, China.\u00a0 The landslide, which is described in a paper just published in Landslides (Sun et al.<\/em> 2022<\/a>), caused extensive damage.<\/p>\n

The impact of the landslide is nicely captured on Google Earth.\u00a0 The site is at 41.8508, 123.8828 – this is an image from November 2014:-<\/p>\n

This was the largest in a series of landslides that occurred in this coal mine – Sun et al.<\/em> (2022<\/a>) describes over 100 landslides over the life of the mine, which seems like a surprisingly high total, especially given the proximity of infrastructure to the edge of the workings.\u00a0 The authors note that these landslides caused “severe damage to buildings, underground pipelines, roads, and railways”.<\/p>\n

The 26 July 2016 landslide was on a different scale however.\u00a0 The landslide was 350 m long and 500 m wide, with a volume of 3.1 million cubic metres.\u00a0 It destroyed 40 houses as well causing damage to roads, railway lines, equipment, and buildings.<\/p>\n

The landslide itself was a rotational failure in the upper part of the highwall, with a fragmented debris trail on the lower slopes.\u00a0 The image below, from Sun et al.<\/em> (2022<\/a>), shows the aftermath of the rotational failure:-<\/p>\n

It is interesting to note that the Google Earth imagery shows a substantial landslide on the lower slopes prior to the this very large failure.\u00a0 Sun et al.<\/em> (2022)<\/a> do not appear to consider this to have been a factor in the main landslide event, which is interesting.\u00a0 The final trigger for the landslide was heavy rainfall.<\/p>\n

The July 2016 Fushun landslide is a very good example of the ways in which long wall mining can trigger destructive instability.\u00a0 In a site with houses located so close to the mining operations, there is a particular responsibility to manage the slopes.\u00a0 The paper rather carefully reports multiple destructive landslide events in this mine; I hope that lessons have been learnt since this major failure.<\/p>\n
