Would fibre-optic cable solve mine automation problems?

Could fibre-optic cable solve the problems of automating underground mining?

Fibre-optic cable can be used, but it can snag, and the mining vehicle still needs a processor at the other end.

Fibre-optic cable can provide a connection underground, but mines contain many opportunities for a trailing cable to snag. The vehicle also still needs a processor at the other end. Changing the communications link therefore leaves both a physical cable-handling problem and electronics aboard the mining machine.
