摘要(Abstract)：

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。
