More insane pictures of Russian potash mining destruction

The recent catastrophic accident at Uralkali’s Solikamsk-2 potash mine is not an isolated case.

Over the past thirty years, numerous similar accidents, caused by sudden surface subsidence, occurred at potash mines located in and around Berezniki and Solikamsk cities in the Perm Region of Russia.

Berezniki and Solikamsk, the second and third largest cities of the Perm Region, sit on abandoned and existing underground potash mines, some of those located as close as 200-300 meters from the surface.

First major sinkhole occurred at the Berezniki potash mine #3 in 1986. It was later flooded and now has a 210 X 110 meters size.

In 1993-2005, several hundred earthquakes with a magnitude varied from 2 to 5 of the Richter scale, were recorded in the Berezniki-Solikamsk region.

Those countless earthquakes have been caused by collapsing underground tunnels of potash mines, mined out over the 70 continuous years of production.

In October 2006, in order to prevent catastrophic implications of a sudden brine influx, Berezniki potash mine #1 was flooded by Uralkali. After that, three major sinkholes occurred there.

On July 28th, 2007, huge sinkhole appeared on the surface above closed Berezniki mine #1, caused by sudden infiltration of groundwater into underground tunnels.

With an initial size of 50 X 70 meters and 15 meters depth in July, 2007, this sinkhole dramatically expanded to 437 X 323, 100 meters depth crater by November, 2008.

On November 25, 2010, a boxcar sank into a sinkhole at the Berezniki railway station.

Later on, this sinkhole has been expanded significantly and flooded. Railway station has been closed permanently.

In December 2011, a new sinkhole occurred nearby the Berezniki mine’s administrative building.

In September 2012, a truck with a driver and two bulldozers fell into a hole during sinkhole backfilling activities. Regretfully, a truck driver died in this accident.

Currently, this sinkhole flooded and has a size of 132 X 137 meters. In October 2014, seismic activities detected there.

 Because of the continuous surface subsidence processes, multiple cracks appeared in more than 25 apartment buildings in Berezniki.

To this date, about 1200 people had to be moved from their apartments and houses.

According to recent estimates, about 12,000 residents of Berezniki will have to leave their homes in the near future because of possible surface subsidence and sinkholes caused by potash mining activities.

Needless to say inhabitants of this area are living in an ongoing nightmare threatened by the possibility to suddenly sink into the ground.
