Implementation of ultimate pit limit algorithms with microsoft excel

Conference Paper


Abstract


  • The determination of the ultimate pit limit is of vital importance to all open pit mining endeavours. The calculation of the ultimate pit limit is essentially a determination of the greatest economic value of an orebody. There are several commercial programs used by the industry to determine ultimate pit limits; these include the popular Whittle Four-X. In this paper the program UPL is discussed; UPL is designed primarily for undergraduate students as a learning tool. The program is designed to be an adjunct to Microsoft Excel. It has the advantages of its simplicity and low cost, whilst still retaining the ability to calculate the ultimate pit limit with good accuracy for large-sized geological block models.
