FURTHER stoppages of 24 and 48 hours will roll out across the Bowen Basin, beginning tomorrow.
According to industry reports, notice was filed at BHP Billiton Mitsubishi Alliance's Saraji and Norwich Park operations this week.
The notice follows the publication of an open letter to BMA employees this week in local and national media outlets in which asset president Stephen Dumble called on workers to return to work and "make safety your first priority".
Mr Dumble addressed the core unresolved concerns of the enterprise agreement negotations that have dragged on for more than 15 months with the Single Bargaining Unit, comprising the AMWU, CFMEU and ETU.
"This enterprise agreement is about our future, a future that we are already heavily investing in," the letter read.
"We are committed to continuing our strong investment in accommodation to enable more direct employment and to attract more families to our town.
"It is clear that there are no winners from this wasteful industrial action."
More than 4000 unionised mine workers returned to work on Wednesday following seven days of strike action at seven of BMA's Bowen Basin mines.
