A CQUNIVERSITY professor says Adani's $21 billion coal mine will give Queensland an insight into how the future of the coal industry will look.
Resource economist professor John Rolfe said Adani's Carmichael Mine showed "long-term confidence" in the coal industry.
Prof Rolfe said Adani would bring new technology such as driver-less trucks to its Carmichael Mine project.
"If you look at the average coal mine, it would have between 1000 and 2000 employees, but now we're seeing more tonnes of coal per employee with better automation," he said.
Adani plans to produce 60 million tonnes of coal per year, making it Australia's largest operation.
"As old mines close down and new mines start up we're starting to see these new operations are getting more technology to make them more efficient," Prof Rolfe said.
"(Adani) has kept going with their development and approval process when other mines were cutting back.
"This is essentially a signal that Adani believe in the long term that coal is a very important commodity."
