Trade union leader Vyacheslav Sidorov said Friday that work at all eight coal mines operated by Mittal Steel Temirtau had resumed, but said not all miners were satisfied with the salary agreement reached on October 4.

Average monthly wages for miners will double effective from October 1, Kazakhstan Today reported.

The mining strike started on September 25, five days after a gas explosion killed 41 workers at a Mittal Steel Temirtau coal mine.

Arcelor Mittal said the strike led to a 30% decline in daily production at its regional steel mill.
