An investigation is underway by mining company Anglo American to determine why water inundated part of an underground coal mine near Middlemount, north-west of Rockhampton in central Queensland.

An on-site dam storing water at the Grasstree mine broke its bank on Thursday, causing water to gush into the mine, according to the Construction, Forestry, Mining and Energy Union (CFMEU).

It says three employees were forced to climb onto machinery in the mine to avoid being swept away.

A spokesperson from Anglo American said there were no injuries and they have notified the Mines Inspectorate of the incident.
