Just over a month ago, the Grosvenor coal mine in Queensland exploded, causing a massive methane plume and doing more damage in an hour than 10,000 tree saplings could offset in 10 years.

    So when they finally close all the coal mines,

    OK

    and seal all the shafts and fill in all the pits, they’re also going to have to

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

    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.

    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.
