I've read today on Facebook that smoke is currently bellowing out of the drift at Daw Mill. Don't know much more than that but sounds like the fire is still burning!

I'd have thought they would have done something like seal the shafts and drift and either fill it with water or pump nitrogen in to kill the fire...The longer it's left the worse it's going to get, plus chances of methane explosions.

Here is a link to the news report www.bbc.co.uk/news/uk-england-coventry-warwickshire-24759956On the Facebook page a few people are slating UKCoal. Its said that when the ventilation was turned off the ventilation current reversed. It is also said that the drift hadn't been sealed as the management at the mine are not sure what to do regarding possible pollution of the water table as the mine floods. There is talk of possible explosions at the mine. As the mine is on fire there I would think there is a risk of an explosion from a build up of carbon monoxide not methane, carbon monoxide produces really violent explosions from what I remember when I studied mine ventilation years ago.

It has always puzzled me why some of the places where underground coal seam fires are widespread and have continued to burn for decades or even centuries seemingly with no recorded serious explosions. Centralia Pennsylvania has been burning underground since 1962 and the massive fires in Jahria Bihar in India have burned for more than 100years, these being just two examples of hundreds if not thousands of fires many of which started within old workings and some that were ignited ‘by nature’ at seam outcrops, but with no massive explosions. Maybe it has something to do with the fact that the two examples above are relatively shallow seams and related workings where the ground is fractured to surface, a “Catch 22” situation where the ongoing fires are both exposed to Oxygen and free to exhaust the burning (or unburnt) gasses to open atmosphere, although at some point both these examples of fire must have reached relatively enclosed worked out cavities. www.whatsup-prod.com/project/jahrias-land-of-fire/?lang=en

There`s a big underground fire in Australia,cannot remember the area,but that has been burning for a very long time.
