I'm not a mining engineer but I would think that a basic efficiency will be obtained in deployment of ancillary services.
I set of yellow iron supporting 2 miners in the same location.
Welfare, generators, etc.
It may be that the larger area is easier to work, so why work more problematic areas when met coal is lower price, do it when the price is higher.
Just my thoughts, but it's the basis of any workplace, efficiencies need to be found at all times to maximise profit, and to them there is safety to consider, the larger area may be safer and pose less risk.
