摘要： 基于浮锥排除法基本原理，使用Smart Miner 软件对两露天采场进行全境界优化，将两个不同生产条件的采场合为一个矿区.考虑到不同采区生产技术经济参数不一样，而境界优化结果对这些参数的敏感度较高，所以软件增加了优化中识别开采对象所在分区，按所属分区的技术经济参数进行优化的功能；同时采场开采范围受地表构筑物影响，因此软件新增在任何约束范围进行境界优化功能.以司家营露天矿区为例分别在有约束和无约束条件下根据分区参数进行优化.结果表明，地表构筑物对最佳境界的约束“很硬”，由此少采1亿t矿，且在-202m水平开始形成挂帮矿；如果这1亿t矿仍然露天开采，那么地表构筑物移除费用必须小于3.4亿元.

Abstract: Based on the theory of floating cone exclusive method， the ultimate boundary of two open pits in different producing conditions was optimized together by Smart Miner software. In view of the technical and economic parameters being different in open pits and the optimization results being sensitive to these parameters， the software incorporated some functions to indentify the partitions of mining objects and optimized the boundary by the corresponding parameters in each partition. Meanwhile， the software incorporated the function of optimizing boundary in any constraint ranges for the mining range being restricted by the surface structures. Taking Sijiaying open pit as an example， the ultimate boundary was optimized with restrictions and non-restrictions according to the parameters in different partitions. The results showed that the surface structures which caused 0.1 billion ore loss were a strong constraint to the optimum boundary. The 0.1 billion ores formed hanging wall ores from -202m level. If the hanging wall ores were still mined opening， the cost of moving surface structures must be less than 0.34 billion.
