Raspadskaya plans to invest $1bn to increase its coking coal output to 18.5 million tons by 2015 and to combat the effect of the deadly methane explosions at the Raspadskaya-Koksovaya mine in May 2010.

The company plans to invest $175m this year, $225m in 2012, $227m in 2013, $167m in 2014 and $155m in 2015.

Raspadskaya aims to raise 19% of its output from 7.2 million tons in 2010 to 8.5 million tons this year by increasing production from the Raspadsky open-pit mine, the Raspadskaya-Koksovaya mine and recovery from the Raspadskaya mine.

The firm further expects to increase the output to 12.8 million tons in 2012 and to 16.8 million tons in 2014.
