Abstract:In order to promote standardization of probable study work for economic signification of deposit development, help geological workers in the work, developed the Probable Study System for Economic Signification of Deposit Development (PSDD). PSDD can generate the probable study requirements of all charts and report, given the economic evaluation index. The chart for the.xls format, and the report for the .doc format. The static index includes the total profit of the mine, the rate of profit of capital and the static payback period. The dynamic indexes include the financial net present value, the financial net present value rate, the financial internal rate of return and the dynamic payback period. Through the practical application, PSDD achieved the desired results. PSDD as tool of probable study for Economic Signification of Deposit Development, to enhance research level, normative research results, improve research efficiency play a positive role. However, the application effect of PSDD is closely related to the representation of the selected parameters, and the market investigation should be carried out before use.
