将层状矿床所包含的物料划分成松软层、岩石层和有用矿物层等三种类型，提出了露天开采工艺的指标评价体系，并应用专家系统、计算机模拟、系统分析及评价等方法，建立了层状矿床露天开采工艺的优化决策模型，并应用该模型对ＨＷＳ露天矿开采工艺系统进行了优化。 The material included in the stratiform deposit is divided into three types: loose layer, rock layer and useful mineral layer. The index evaluation system of open-pit mining technology is put forward and the methods of expert system, computer simulation, system analysis and evaluation are established The optimization decision model of the open-pit mining process of stratified deposit was established, and the model was used to optimize the mining process system in the open pit of HWS.
