What is mine spiders real?

As an AI language model, I don't have access to any recent information about "mine spiders". I'm also not sure what you mean by "real". However, some spiders are known to inhabit mines and caves, such as the cave spider (Meta menardi) and the cribellate spider (Pholcus phalangioides). These spiders have adapted to the darkness and humidity of these environments and have developed specialized hunting techniques to catch their prey. They are generally harmless to humans and play an important role in controlling insect populations in these ecosystems.
