【摘要】 利用系统分析的方法研究了在考虑土地资源综合利用情况下的露天开采境界优化问题，建立了联合开采矿床露天开采终了坑用作地下开采尾矿库这一特殊情况下露天开采境界优化的计算机模型，并用实际矿山对该模型进行了检验，得出了满意的结果。更多还原

【Abstract】 Taking into account the comprehensive utilization of land resources,open pit is optimized through systematic analysis. For a mine where a combined open pit-underground mining is used and where the final pit will be used as a tailings Pond for underground mining,a computer model for optimization of pit limit is established and verified in field,providing satis factory results.更多还原
