While increases are seen in all three sectors, coal, mineral mines and quarries, the largest increase is seen in coal - especially in matters related to mine worker safety and health.
Each complaint requires, on average, five inspector-days to investigate and resolve.
Latest figures show 134 confidential complaints have been made since the Queensland government's statewide safety resets in July and August 2019, up from 104 in 2018-19.
Queensland mines minister Dr Anthony Lynham said the inspectorate expected a near doubling of complaints by the end of the 2020 financial year.
"The increase in confidential complaints shows the safety resets are working by encouraging mine and quarry workers to report anything they feel is a potential safety risk," he said.
For the 2019-20 financial year the Mines Inspectorate has conducted 1015 inspections with 215 of those being unannounced inspections.
The inspectorate has also conducted 76 audits.
Meanwhile the mining regulator has accepted and committed to implementing each of the four recommendations it has received in the Brady Report.
These include adopting the serious accident frequency rate as a measure of safety in the industry; adopting the high potential incident frequency rate as a measure of reporting culture in the industry; and establishing a specialist, dedicated data analytics unit to collate, categorise, actively search and identify concerning trends in incident data for the industry.
Lynham acknowledged the mining industry, unions and workers commitment to the recommendations outlined in the Brady report.
"Queensland now has the toughest mining laws in the planet, and there is more to come," he said.
"We have listened, we enacted the safety reset and we have actioned changes.
"At the end of the day, nothing is more important than the health and safety of our 53,000 mine and quarry workers."
