A computerized cost estimating program developed with the use of the Lotus 1-2-3 spreadsheet program has produced dramatic savings in preparing estimates for operating costs, equipment fleet size and manpower requirements for underground mines. The program is used by Dynatec to support its consulting engineering projects, particularly feasibility studies. The 'first principles' approach is used to prepare detailed estimates under direct labour and supplies categories and maintenance costs for each mining operation. User notes have been developed to guide the estimator and ensure appropriate consideration is given to the specifics of the particular mine. A typical case history is illustrated and the ease by which alternatives and sensitivity analyses can be prepared is demonstrated.
