The definition and the principle of the optimal mining geological body are mainly introduced,the dynamic eco-nomic evaluation of the optimal mining geological body is conducted by using dynamic programming method to as to formulate the mining plane. Taking a open-pit mine as the study example,the mining-stripping plan of the mine is optimized,the annual amount of mining area(mining quantity,stripping quantity,metal quantity) and the net present value of every year are ob-tained,which indicated that the optimal geological mining model is feasible,besides that,the practicability of the application of dynamic economic evaluation method in the optimal of mining-stripping plan is verified.%介绍了地质最优开采体的定义、产生的原理,并应用动态规划法对地质最优开采体进行动态经济评价,从而制定采剥计划.以某露天矿为实例进行了采剥计划优化,得到了矿区每年的开采区域(采矿量、剥离量、金属量)及每年的净现值,验证了地质最优开采体模型及其动态经济评价在采剥计划优化中的实用性.
