摘要

在露天矿山爆破作业中,为充分考虑各工序环节间的衔接,合理配置矿山生产资源、降低总体能耗,提出爆破共享控制理论.结合矿石宏观破碎和细观损伤的关联关系,创新地提出铲运过程的矿石损伤模型.通过优化各工序作业的衔接,考虑生产设备的磨损、折旧等因素,将钻孔、破碎用电(油)、现场装药爆破、铲装、运输等环节的总能耗进行合理分配,提出各工序的评价和控制指标,建立爆破共享控制模型.结果表明:矿石损伤模型揭示了岩石爆破破坏过程的多阶段特性,通过调控破碎量对破碎能耗进行有效预测,拟合精度达到0.8以上,能够实现破碎机运行效率的优化和破碎能耗的降低.通过爆破共享控制模型,计算得到爆破参数设计的最优解,建立约束条件下最优综合能耗公式,能够实现各环节能量的精准调整,为矿山作业的高效、安全和可持续发展提供了有力支持.

Abstract

Efficient coordination between different processes is crucial in optimizing resource allocation and min-imizing energy consumption during blasting operations in open-pit mines.To address these challenges,the theory of blasting sharing control is proposed,which integrates macroscopic ore fragmentation with mesoscopic damage analysis and introduces a novel ore damage model for the shoveling process.By optimizing inter-process connections and con-sidering factors such as wear and depreciation,a comprehensive energy distribution model is developed across drill-ing,crushing,blasting,shoveling,and transportation processes.Evaluation and control indices are proposed for each process,leading to the establishment of a blasting sharing control model.The results demonstrate that the ore damage model reveals the multi-phase characteristics of rock blasting failure and effectively predicts the crushing energy con-sumption by regulating fragmentation levels.With a fitting accuracy exceeding 0.8,this model optimizes the crusher operations while reducing energy consumption.Using the blasting sharing control model enables calculation of the op-timal solutions for blast parameter design while establishing an optimal comprehensive energy consumption formula under the constraint conditions,thus enabling the accurate adjustment of energy at each link and providing strong support for efficient,safe,and sustainable mine operations.
