(EnergyAsia, September 5 2012, Wednesday) — Brazilian mining company Vale SA said it has resumed production at its Carborough Downs coal mine in the Central Bowen Basin in Australia’s Queensland state.

Citing safety reasons after detecting abnormally high levels of carbon monoxide, the company declared force majeure and stopped work at the metallurgical coal mine May 31.

No employees were adversely affected and no environmental damage occurred, Vale said.

“Carborough Downs has resumed production at a safe rate. Output will gradually normalise as the remaining operational and geological issues are resolved. In the second quarter of 2012, Carborough Downs produced 82,000 metric tons of metallurgical coal,” it said.
