well,maybe a longwall,still bet they never get 8 mil tons out of it.
It is a longwall mining system though the media report wasn’t particularly detailed (when are they ever?). The picture shows the shear in the foreground and I think the thing in the background is the armored face conveyor.
Based on the relative size of the man in the picture, it’s a fairly massive longwall so 8 million tons is certainly possible though it will depend on maintenance downtime.
