In the near future, further miniturisation of the electronics, and better smarts will mean that this kind of technology can be used to continually update the topography of an open cut mine, with swarms of such robots preceeding ultra large automated vehicles, helping automated shovels load automated trucks. Perhaps they will even be able to replace the truck fleet, with millions of tiny robot flies moving enormous tonnages of ore without the need for roads, ramps etc. Just the saving in the profile of the open cut pit would change the economics of mining.
Underground mines could benefit too, with robot miners like the fly moving in to survey the mine after blasting - testing the air, rockface stability, everything. There is also my previous post of the robot crawlers which could also operate underground in very confined spaces.
There is a lot to consider, and the extraterrestrial problems being solved by robots can also be applied here, today.
