A bushfire north of Fingal has burnt within 500 metres of an exposed coal seam, however fire authorities are confident of carrying out required asset protection measures should it flare up again.
Fire crews used heavy equipment in an attempt to cover and protect former Duncan Colliery infrastructure with fears that, if the coal seam is impacted by fire, it could burn for months similar to the Hazelwood mine fire of 2014.
Tasmania Fire Service acting regional fire chief Ian Bounds said mild conditions in recent days had reduced the risk in the area.
"We're now shifting our focus to a number of other issues with the progression of that fire in a southerly direction towards Douglas-Apsley and also some assets around the coal mine, which are certainly of concern," he said.
"[The fire is] less than probably half a kilometre [from the coal seam], but the fire is backing town, it's quite benign.
"The risk will be if the fire flares up as it approaches that coal mine. That's what we're working on in the next few days.
MORE ON THE FINGAL FIRES:
"It is very close and we're working closely with [mine] management to address any issues we've got there."
Temperatures are expected to remain in the low-20s until later in the week, and patchy rain could also cross the East Coast on Tuesday.
More dangerous fire conditions could occur on Thursday.
The TFS has issued a series of advice and watch and act warnings for Fingal and surrounding areas on Monday, including for smoke and embers.
Mr Bounds said the community could be assured that appropriate resources were being allocated to the fire.
"We're very well resourced with our Sustainable Timber and Parks and Wildlife personnel," he said.
"We believe we're well resourced to deal with that issue."
Mr Bounds addressed the media at Launceston Airport on Monday morning where 41 Tasmanian firefighters flew out to support the RFS in New South Wales.
The Pelham fire is still within containment lines, while one of the nine Strathgordon fires remains of concern.
