The spokesman in the Kemerovo Region's Kuznetsk Basin, which with total estimated reserves of more than 11 billion metric tons is one of the world's largest, said the miner was in a stable condition in hospital. Fourteen mine workers were underground when mud and water suddenly flooded a gallery.
Russian mines have been hit by a series of fatal accidents in recent years attributed by many to poor maintenance due to the coal industry's chronic underfunding.
Two miners died and two others were injured in an accident on March 4, apparently caused by a methane explosion when the four men were installing a protective fence.
The first deputy governor of Kemerovo Region proposed after the March accident that coal companies and mine owners close ageing mines that posed a safety threat to workers.
