摘要

Bear Valley in the Western Middle Anthracite Field of Pennsylvania was evaluated as the site for an open pit mine capable of producing sufficient anthracite to sustain an electric power generating plant. A computer model was used to estimate reserves and stripping ratios from data provided by USGS. This infor¬mation together with equipment performance characteristics was applied to a simulation model to determine truck fleet sizes for shovels and front-end loaders. Capital investment and cost3 were calculated and a discounted cash flow analysis was performed to determine rates of return for a range of selling prices. A brief background study of the area is included.
