The $5 million trial project looked at new drilling techniques at the Mount Thorley-Warkworth site to capture methane emissions released during mining.
Coal & Allied's managing director, Bill Champion, says it will go along way to reducing the company's carbon footprint.
"It has been designed to just flare off the methane to begin with," he said.
"We needed to get it up, get it running, prove that we could actually recover the methane from the coal bed - so once that's occurred really the next stage is to determine whether we've got quality enough methane gas and quantity enough methane gas to actually look at turning that into some sort of commercial proposition."
