There's a good BBC article on it here, with a lot of detail about the people behind the tunnelling schemes, and the horror of digging in complete silence, listening out for enemy miners who might be just inches away:
About a year later, the battle of Messines (https://en.m.wikipedia.org/wiki/Mines_in_the_Battle_of_Messi... ) saw larger mines, some of which with over 40,000 kg of explosives.
Five of them weren't detonated. One of those exploded in 1955 after a lightning strike. Most likely, four others are still lying below ground. It's anybody's guess whether they still are dangerous and might detonate one day.
