Queensland's peak mining association has thrown its weight behind a proposed bill that could hold companies and bosses criminally responsible for workers' deaths, as the state reels from its seventh fatality in just 18 months.

Pressure has been mounting on the state to improve mine safety after the death of 57-year-old Ipswich man Brad Duxbury was killed at the Carborough Downs mine site in central Queensland on Monday night. 

The draft industrial manslaughter bill is currently being discussed by key industry stakeholders, and will likely be introduced into the Queensland parliament next year.
