| Abstract: | on the basis of a brief analysis and evaluation of the existing method for determining the open pit mining limit, this paper points out the limitation of the existing method based on static economic analysis, and puts forward a new method based on dynamic ecomomic analysis for determinig the open pit mining limit. In this paper the influence of mining sequence, working slop angle, mining intensity, discount rate, variation of price and cost of ore on the open pit mining limit has been discussed. |
