Flooding at a PAO Uralkali potash mine in Russia’s Perm region has increased four-fold in the last two weeks, and a nearby sinkhole is almost 300 feet across.
The average brine inflow to the Solikamsk-2 mine increased from 200 cubic meters an hour to about 820 cubic meters an hour between Jan. 22 and Feb. 6, the world’s largest potash miner said today in a statement. A sinkhole that opened up east of the mine, swallowing local summer homes, has widened to 87 meters (285 feet) by 58 meters and is about 75 meters deep, it said.
