List of landslides in mining
Landslides in mining arise, for example, from ground fractures (failure of the load-bearing capacity, for example due to the rise of the groundwater) and settlement flow .
They include:
- Demolition of slopes in opencast mining
- Demolition of heaps
- Embankment slides on lakes in the former opencast mine , which were formed by the discharge of groundwater or surface water.
Settlement flow slides can be triggered especially when the soil liquefies. The sliding process takes place in an avalanche-like and extensive manner in seconds to minutes. If the dump remains in place for longer, there is no decrease in the risk of liquefaction.
list
| date | Location | location | description | Volume (m³) |
|---|---|---|---|---|
| 2nd February 1959 | Concordia pit | Nachterstedt | Demolition from the 86 meter high edge of the opencast mine, which rolled over a miner, two skid loaders and a whole haulage train. | 6,000,000 |
| October 21, 1966 | Aberfan disaster | Aberfan , Wales | Demolition of part of a dump. 144 dead. | 110,000 |
| May 21, 1981 | Pit New Concern | Luckenau , Burgenland | two dead | |
| January 1987 | Remaining hole in Laubusch , today Erikasee | Hoyerswerda | 12,300,000 | |
| November 1991 | Rest hole Kleinleipisch | Lauchhammer | Compaction blast caused landslides. A photographer drowned in a tidal wave on the other side of the lake. | |
| April 1995 | Grosskayna-Süd opencast mine | Saalekreis | 500 m² piece of the bank slope slides into the water hole. An excavator driver was killed. | |
| September 1996 | Rest hole Burghammer | Hoyerswerda | Blasting caused a slide and buried mining technology under itself. | 4,500,000 |
| 1997 | Koschen opencast mine | 2,200,000 | ||
| 1998 | Partwitz lake | Oberspreewald-Lausitz district | The lake is based on the Scado opencast mine . About 12 hectares of forest and grassland slipped into the open pit lake during the flooding. | 4,500,000 |
| May 6, 1998 | Koschen opencast mine | Senftenberg | 1,500,000 | |
| June 19, 1998 | Koschen opencast mine | Today Geierswalder See . During a test blast, considerable amounts of earth were set in motion and dragged the 55-year-old demolition expert with her; she was never found. | ||
| October 12, 2000 | Residual hole D / F | Knappenrode | After a compaction blast, almost the entire unsecured foreland slipped into the remaining hole over a width of 700 m. | 630,000 |
| 2005 | Knappensee | Bautzen district | Most of the embankments are part of the inner dump of the former Werminghoff I opencast mine. The sandy dump material is mostly loose to, in some areas, very loose. It has properties that are decisive for a risk of liquefaction. The landslide occurred in the area of Koblenzer Straße. The lake remained closed in 2017. | |
| March 2006 | Altdöberner See | Altdöbern | Greifenhain opencast mine . Landslide near Altdöbern . Another landslide followed in 2008. Large areas around the lake are designated as restricted areas because of the danger to life. | 2,700,000 |
| Winter 2008/2009 | Silbersee II | Haltern am See , Recklinghausen district | The area of about two soccer fields slipped. | |
| July 18, 2009 | Lake Concordia | Nachterstedt | A whole slope with two houses slid 500 m wide into the lake. Three people perish. The corpses stayed gone. | 4,500,000 |
| October 12, 2010 | Bergener lake | Hoyerswerda , Bautzen district | Spreetal opencast mine . Ground failure 2 kilometers long and 600 meters wide. 83 sheep and five trucks sank in the floods. A truck driver was rescued by a helicopter. | 4,500,000 |
| January 6, 2014 | Romonta pit | Amsdorf | Earth masses began to move. As a result, a stripping machine slipped and was spilled. | |
| End of February 2017 | Silbersee II | Haltern am See , Recklinghausen district | An 80 meter long and about 30 meter wide embankment broke off after rain in the area of the Franzosenweg. | |
| June 29, 2016 | Lake Concordia | Nachterstedt | On June 29, 2016, another landslide occurred during renovation work, in which around 1.7 million cubic meters of earth slid off. | 1,700,000 |
| 13th September 2018 | Senftenberger See | Oberspreewald-Lausitz district | The island is an inner dump of the former opencast mine. Earth masses and rows of trees loosened on an island due to settlement flow of the embankment. The bank area around the lake has been closed. | |
| 18th September 2018 | Felixsee | Spree-Neisse district | The lake was created by the flooding of an open- cast lignite mine . A recreational diver noticed unusual changes on the bottom in 2018. |
