US China Mining Group said that its retrofit program at the Xing An mine in the northern region of China's Heilongjiang Province is on schedule and the mine is expected to resume full production in May 2011.
The company began a program in December 2009 to upgrade this mine, which produces high-quality thermal coal.
These improvements were intended to increase efficiency, safety and boost production at the site.
Operations at the mine will be transitioning from room-and-pillar mining to long wall mining process, which will enable year round coal production, the company said.
US China Mining Group is engaged in coal production and sales by exploring, assembling, assessing, developing and mining coal properties in China.
