Looks like a quarry to me!
Most modern mines are!
Even modern underground ones are usually worked by a process of extraction called trackless haulage. Which basically involves using diggers, excavators trucks and the like which just looks like underground quarrying.
Some of these machines are operated using remote radio control and if the operator of them enters a stope he can be severely reprimanded.
In modern mining production is nearly everything!
The extraction bit would be 'block caving' or similar.
The haulage bit, trackless vs tracked is interesting, tracked still has its place where the roadways are fairly straight and long back to the shaft it may be the more efficient method, even beating conveyors (easier/quicker to change out a problem wagon than fault find and repair a conveyor). Gets to a point where it makes sense to sink another shaft though, down to economy..trackless loaders/scooptrams are not efficient tramming great distances, I would be interested to know how the cut off point is decided in practice.
Theres some good photos on here of a remote scoop being operated at Wheal Jane, I'd guess that would be a UK first but worldwide who knows...
Dont know about coal, but down here production always was the be all and end all
