Coal Mining Process Input Output Processes

Jan 01, 2013 UNDEGROUND MINING AS A SYSTEM SIMULATED Coal working face is a technological system with layers of rock and coal (the source of a product) and machines for coal mining as technological objects. Computer simulation can estimate the amount of coal mined and the amount of energy and other resources required for this process

    Aug 21, 2013 There is substantial potential for energy efficiency improvements in glass manufacturing. Estimates range from 20% to 25%, mainly focused on the extremely energy-intensive melting and refining process.Energy used in other key glass-making processes, such as forming, is highly variable depending on the product, so those processes don't have the same potential for efficiency gains

Our results suggest that the premise upon which the South African government's proposed minerals policy is based, i.e. that “the mining industries have the capacity to generate
