摘　　要：基于矿体模型提出了几何定界和价值定界算法,对露天境界的圈定和优化进行了研究,以期得到一个经济上合理,技术上可行、安全的最终境界。首先将矿床的数据及开采技术条件输入到计算机中,建立矿体模型。并根据岩石存在各向异性这一属性,对最终帮坡角进行了分区。然后利用几何定界和价值定界的计算机可执行算法,得到最优境界。最后将某露天矿实际数据与理论的进行对比,并进行了境界分析。In order to obtain an economically reasonable,technically feasible and safe final boundary,based on ore body model,this paper mainly proposes geometry boundary algorithm and value boundary algorithm and studies the delineation and optimization of open-pit mine boundary.Firstly,the ore deposit data and the mining engineering factors are input into computer to establish ore body model.According to anisotropy property of the rock,the final slope angles are divided into different districts.Then,the algorithm can be implemented by the computer which can do geometric boundary and value boundary algorithm to obtain the optimal boundary.At last,the actual data of the open-pit mine is compared with the theoretical data,and boundary analysis is implemented as well.
