Conventional mining vs surface miners - Mining Mirror Online

Nov 19, 2018  An analysis of the two mining methods further demonstrated that fuel consumption is about 79% lower — and therefore also CO 2 emissions — with surface miners than when using the conventional method. The lower number of machines in use additionally has a positive effect on risk management, because fewer machines mean a reduced risk of ...
