Abstract

Abstract: Based on the ecological-economic parameters and occurrence of orebody， the cone exclusive method was used to design the profit-maximum pit without constraint. According to the location of surface structures at the ore district， constraint lines were built to restrain optimization region， and the profit was obtained from ores outside constraint lines by underground mining. An ecological costs model of mine was built to calculate the ecological cost of two optimization schemes. The results showed that under only considering economic condition， it’s suitable for a unrestrained pit to mine if the moving cost of surface structures is less than 0.99×10⁸￥(NPV). The restrained pit is the best choice while ecological costs are considered.

Key words: open pit mine, ultimate pit, ecological cost, profit, surface constrains
