Comment on Huge methane plume from Queensland coal mine explosion underlines case for rapid closure

So when they finally close all the coal mines,

and seal all the shafts and fill in all the pits,

Hmmm. Will they really? That’s a cost with no revenue. I’d go bankrupt if I were them.

they’re also going to have to go and cap the thousands upon thousands of boreholes because they’re a direct line to the remaining seams below, and they’ll basically vent forever.

Well I gas that seems more likely…

They are forced by the state government to put aside money for future rehabilitation.

Something else to point out is that “huge methane plume” is actually methane that is always there. It’s just that normally there is a huge amount of forced ventilation into (and subsequently out of) underground mines and while that is working this methane plume is diluted to much lower levels.

  Oh, my bad. I thought that the methane was kinda trapped underground with the coal and was released by mining/boring.
