Context for the Tumbi Quarry landslide – an image gallery for quarry and open cast landslides
Posted by Dave Petley
Thanks to everyone who has submitted ideas of images of the landslides in and around quarries and open cast mines, in response to the Tumbi Quarry landslide posts. This is a collection of images of landslides caused by mining and quarrying. I will add to it through time, so please do keep suggesting additions.
The Yallourn open cast mine landslide in Australia:

Chuquicamata mine, Chile, pit wall failure in 1969 (see the great resource on mine wall failures here)
Mine wall failure at Round Mountain in Nevada (courtesy of Dan Bartlett)
Start:
During:
After:
Huckleberry Mine, SE of Smithers BC, Canada, June 2007
Courtesy of Jimmy James: “East Zone Pit north wall failure. (2×10^6 m^3 est volume). No injuries or equipment damage were reported and mine life was nearing conclusion in that pit so there was minimal loss of production. Mining is ongoing in an adjacent pit.”

Another mine level view looking slightly east of previous view (http://goo.gl/NfG3J):
BC EMPR Mines Report 2007 (this includes a view of failure toe and brief discussion of mine geology on page 6)
The 2011 Mine Optimization PDF report discusses the geology of the mine area, including in the completed East Zone Pit. Pages 37, 40 illustrates faulting and slide location. Pages 65, 66 illustrate and describe dyke and faulting along the north wall of the Main pit, just west of the east pit.
The Pantai Remis landslide in Malaysia (the best landslide video of all time):
As noted above, I’d like to add more to this collection, so your suggestions are welcome.
As a contribution to this image gallery, here are some links about the Savage River mine’s collapse (reports are dated to July 2010).

On picture two, damaged machinery appears useful to consider the size of the event.

In researching additional images for this gallery, i found on the landslide blog a post from July 2009 about an event occurred in a former mine in Germany :

Such an event reminds that former mines remain dangerous, even after many months or years of inactivity, and need huge stabilization and mitigation works to allow a proper reconversion of the site.
To continue the gallery, here are some images of a slope failure occurred whitin the Grasberg mine’s open pit (province of Papua, Indonesia). I didn’t find the date of occurrence :

In looking for others images, i just found an interesting blog which aims to gather mining incident photos :

Using the label “highwall collapse” within the blog gives some interesting pictures, especially these ones from two majors events :
http://www.miningmayhem.com/2009/05/total-highwall-collapse.html
http://www.miningmayhem.com/2011/08/sunrise-dam-highwall-failure.html
The location and date of the first event seem to be unknown. The second event occurred in 2011 within the Sunrise Dam mine (Western Australia). Further details on the mine are available here :
