Glencore’s Hail Creek coal mine in the Bowen Basin near Mackay will make more than 400 workers redundant due to a recent restructure of the mine.

Meetings were held by the global resources giant on Monday at the Mackay showgrounds, to announce its reconfiguration of the two dragline operation.

Over 30 per cent of the mine’s current workforce is expected to be cut, reducing the numbers of workers from 1,360 to 930.
