An underground coal miner who worked in central Queensland has become the 19th person diagnosed with black lung disease in less than two years.

The disease, once thought to have been eradicated in Australia, has recently re- emerged and the mining union has blamed poor dust management practices at mine sites.

The CFMEU is demanding mining companies contribute 10 cents for every tonne of coal produced in Queensland to a support fund for victims.

The union says the number of affected workers will rise in coming years, as the effects of poor dust control practices and substandard health checks on workers come to light.
