A ninth Queensland coal miner has been diagnosed with coal workers' pneumoconiosis.

A spokesperson for the Department of Natural Resources and Mines said the 62-year old underground coal miner works in the Bowen Basin, where the state's eighth case was also recently confirmed.

A "perfect storm" of regulatory failure, indifference from the mining industry, poor dust control and patchy health monitoring has been blamed for the re-emergence of the potentially fatal disease.

In the eighth case, the 55-year-old underground coal mine worker had worked in the industry for 20 years, including several mines in central Queensland's Bowen Basin.
