Current status and development trend of deep hole bench blasting technology in open-pit mines

  • 摘要: 随着信息化革命进程的推进、资源开发和环境保护理念的提升,近来年国内露天矿山深孔台阶爆破技术在智能化、绿色化的爆破开采理念下快速发展。在爆破器材方面,电子雷管得到大量推广应用; 在爆破智能化方面,集成了智能钻机系统、智能设计系统、炸药现场混装作业体系的爆破技术基本成型; 在爆破绿色化方面,爆破振动预测理论及控制、爆破粉尘控制、冲击波与噪声防治等有效控制了爆破过程产生的有害效应,逐渐达到绿色环保爆破的要求。同时,分类整理了爆破器材和爆破技术存在的问题,指出了露天矿山绿色智能爆破今后发展与研究的方向。
