Edited this to separate burning lush caves to a stand alone bug report. See MC-219824

This would imo most easily by fixed by making mineshaft wood and logs generate with a minecraft:non_flammable:true tag or something like that

after being broken by a player it would revert back to normal flammable wood

Or implement petrified planks, fences and logs for mineshafts.
