基于Surpac的铜陵新桥矿床露天开采境界优化

矿床的境界优化就是要设计一个最为接近理想状态的模型,使矿山企业利润最大化,在满足经济和边坡角几何约束的条件下,设计一个最终开采境界.基于三维地质矿业软件,可以将三维可视化技术与矿床的后期开采、生产进度编排进行紧密的结合,完成矿体形态与工程实体的衔接,其不同于传统境界优化的方法,可以在三维空间内进行境界优化的应用和研究.本研究选取SURPAC三维地质矿业软件系统,结合铜陵新桥矿床的实际需求,基于三维数字矿山模型,使用L-G算法规范的数学逻辑结构对露天采场进行境界优化.其结果可以为扩大经济效益提供详实的数据基础,并为新桥矿床开展更为合理的开采生产安排提出合理化建议.

Surpac-based open-pit mining limit optimization for the Xinqiao ore deposit,Tongling

Deposit limit optimization is design of a closest-to ideal model to maximize mine profit.It is to design an ultimate mining limit after economic and slope geometric constraints are met.Three-D mining software can closely combine 3-D visualization technology with late mining,production progress arrangement of a deposit,achieving the alignment of ore body form with the mining engineering entity.Different than traditional limit optimization,it can be optimized in 3-D space.This paper used Surpac 3-D mining software,considered the actual need of the mine,is based on 3-D digital mine model to perform open-pit limit optimization using L-G algorithm standard math logic structure,giving suggestions for more reasonable mining of the Xinqao deposit.
