【摘要】 研究借助SURPAC软件对石宝铁矿进行三维矿体建模并进行了境界优化。分析讨论了浮动圆锥法与L-G图论法在不同边坡角度和不同销售价格下优化结果的差异,并对两种算法的效率进行了对比,最后提出了改进算法,并用改进算法对矿体进行了优化,其结果均优于单独使用L-G法和浮动圆锥法的计算结果。更多还原

【Abstract】 With the help of SURPAC software,three-dimensional modeling of Shibao iron orebody is built and boundary of the mine is optimized. The differences of optimization results between floating cone method and LG graph theory at different slope angles and different sales prices are analyzed and discussed. Efficiencies of the two algorithms are compared. Finally,an improved algorithm is proposed and the improved algorithm is applied for optimization of the orebody. Its results are better than those obtained by using either LG method or floating cone method alone.更多还原
