Queensland's Mines Minister Anthony Lynham says he is surprised bureaucrats in his department have been found to have obstructed a black lung inquiry.

A bipartisan inquiry report by a Queensland parliamentary committee found some officers of the Department of Mines and Natural Resources displayed "resistance and obstruction".

The inquiry was set up in response to the "re-emergence" of black lung among Queensland coal miners, as first revealed by 7.30 in 2015.

The committee today handed down its second report, making 68 recommendations, including setting up a new independent mining health authority and reducing the permissible exposure level to coal dust.

Dr Lynham said he could not commit to any of the recommendations but he would consider them.

"I haven't had a chance to read the report," he said.

7.30 asked the Minister what action he would take in response the committee's finding some members of this department were "argumentative" and "resistant".

"The committee doesn't see my department as I see my department," he said.

"I see hard working public servants absolutely committed to eliminating this insidious disorder from the Queensland workforce."

Committee finds catastrophic failures in handling of disease

The Coal Workers' Pneumoconiosis Select Committee recommended the Public Service Commissioner review the hearing transcripts to ascertain whether bureaucrats gave deliberately misleading evidence.

The committee found there were catastrophic failures at almost every level in the regulatory system, including among health professionals and mining companies, as well as government regulators.

Twenty-one former coal miners have now been diagnosed with black lung disease since its "re-emergence" after a 30-year absence.

The disease, which is caused by the inhalation of coal dust, is both preventable and incurable.

The committee found black lung had never disappeared, and authorities had, in effect, given up looking for it.

It said it was "dismayed" the Mines Department was not informed of a workers' compensation claim for black lung disease in 2006.

Overall, Dr Lynham said he welcomed the findings.

"The Department of Natural Resources and Mines and I will consider the committee's 400-plus page report and its recommendations carefully before responding within the 90 day time frame," he said.

The chair of the committee, Labor MP Jo-Ann Miller, said Dr Lynham was just one of many ministers who had been in charge of overseeing mine regulation in Queensland.

"He has tried as much as he can to get on top of this, particularly with regard to the medical side of things," Ms Miller said.

"But this is a cultural issue, it's an issue in regards to a department trying to whitewash the black lung issue away.

"Well the whitewashing is over."
