Okay, sure … but even 60 meters underground is pretty fucking deep, really. (~200ft, for the metric-challenged folks) Quite the excavation project, if you don’t already have a natural cave. And even a lot of natural caves aren’t quite that deep.
And building something 200-300 meters underground starts to become quite an engineering challenge.

That’s why we use submarines as final strike nuclear platforms. Water blocks explosions nearly as well and a submarine can move out of the way.
On the other hand, 200m down is barely considered underground by miners
