    Activity Based Costing Challenging the way we cost

    Process Costing (PC). The coal mining industry uses 'ton of coal mined' as its unit of measure rather than labour. PC is commonly used as the costing measure in systems where the outputs are continuous (as opposed to batch outputs) and is designed for the accumulation of costs for mass production like units (one ton of coal in our case).

  • Stripping ratio Wikipedia

    Equations. The equations for stripping ratio are, for coal ()for metal ()where volume is typically expressed as m 3 or yd and weight is typically expressed as tonne or ton.. Use. It is common for the stripping ratio to be used as an indicator of economic value for an open pit mine. This is because removal of waste is a cost to the mine whereas mining ore leads to revenue.
