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。
At present, the oxidized ore of Dayao Copper Mine adopts the method of Chasm funnel caving mining. However, the loss value of ore is very high. Although the mine has done a lot of work, it still cannot be reduced to the design target. In view of the current situation, in order to master the flow law of the ore-blasting under the specific conditions of the mine; the relationship between the ore body shape, the stope structure parameters, and the recovery process and the indicators for returning poverty; in order to improve the mining method, structural parameters and recovery The craft provides a persuasive basis. A computer simulation optimization study was launched. The paper describes the experimental method of computer simulation and analyzes the results obtained, and proposes the choices and suggestions that have guiding significance for actual production.
