| 摘 要： | 目前大姚铜矿氧化矿采用的是底盘漏斗崩落采矿法。可是矿石损失值很高,虽然矿山做了大量工作,但是仍然不能将其降至设计的指标。鉴于目前的状况,为了掌握在矿山具体条件下崩落矿岩的流动规律;矿体产状、采场结构参数以及回采工艺与回贫指标之间的关系;以便为改进采矿方法、结构参数和回采工艺提供具有说服力的依据。展开了计算机模拟的最优化研究。论文说明了计算机模拟的试验方法并且分析了所获得的结果,提出了对实际生产具有指导意义的选择与建议。

| Abstract: | The caving mining with rock chute now is employed in the oxidizod ore of Da Yao Copper Mine. However the ore-loss and dilution are too high in Value, and are still unable to be depressed to designed indeces, even though a large amouto of work has been made by the mine. In view of the present situation, in order to control the flowing law of caving ore rock ore occurence, stope structural parameters as well as the relations of workmanship and recovery-dilution indeces under the specific conditions of the mine, so as to provide convincing foundations for improving mining method, structural parameters and workmanship. Therefore the optimization research with computer simulation has been developed. |
