If a historic map for an old, discovered mine isn’t available, how do they map it? I’m assuming it’s too dangerous to go down inside something that old (1800’s) so do they use robots to go look? Or do they use something more advanced like GPR (ground penetrating radar?)
… or do they just say huh, neat, an old mine! And never go in?

The simplest way to map mine, or a cave, is to draw it as you travel through it. Free hand it, use graph paper, use whatever you want. There really isn’t any call for using robotics to map out underground caverns so maps will be created by hand. The extensive French catacombs have been mapped (a little bit) by hand. If you worry about getting lost then leave things behind or tie a rope to yourself so you can follow it back out.
You’ve asked this question in a way that sounds not like a hypothetical (“what would one do if …”) but like it’s already happened several times, and you want to know how “they” did it. Has this happened, even once?
