* Operator said accident had natural cause

(Updates with rescue of trapped miner)

MOSCOW, July 17 (Reuters) - Two miners were missing in an Arctic Russian mine after an accident at a coal face, the owner, a unit of steelmaker Severstal , said on Sunday.

Seventy-six miners working in the pit escaped immediately after the collapse on Saturday evening, which was caused by a geological event, mine operator Vorkutaugol said in a statement without going into detail.

One miner was rescued a day after the collapse, Interfax news agency reported. Two more miners were unaccounted for.

Russia, a major producer of thermal coal and coking coal for the steel industry, suffers regular mine accidents, often due to shoddy adherence to safety procedures.

Russia's creaky infrastructure, negligence and rampant corruption were in the spotlight this week following the worst river accident in nearly three decades, when a tourist boat sunk on the Volga killing up to 129 people.

The last major fatal accident occurred at the Raspadskaya mine in Kemerovo in western Siberia last year, when a methane explosion caused it to collapse, killing at least 66 people.
