Abstract
The Bureau of Mines, through its contract research program, recently analyzed the mining and environmental requirements in the premining stage for copper mining in the northern highland of Wisconsin using the critical-path-method (cpm). However, a step-by-step derivation of the cpm diagram was beyond the scope of the effort. The Bureau's objective now is to show, step by step, how the original hand- computed cpm diagram was constructed. The streamlining (restructuring) of the diagram from the original effort is also summarized. The critical path time (longest time) through the original cpm diagram was 25.12 Yr, excluding public liaison effort. The diagram showed the involvement of the regulatory agency, mining applicant, and public in the premining stage. Analysis of the diagram produced a streamlined version that reduced the critical path time by nearly 7 yr. The cpm construction methodology may be applied to mine planning for any mining operation.
