钻孔爆破是开采作业循环中的基本工序并且在采矿成本中占有很大比重。由于钻孔爆破作业不当而带来的问题会造成每年达数百万美元的损失。正因如此 ,诺兰达技术中心 (NTC)于 1984年开始实施了一项爆破技术研究计划。综述诺兰达技术中心在钻孔爆破技术研究方面取得的新进展。从矿石损失和贫化方面 ,阐述了钻孔爆破对诺兰达公司的影响。最后 ,分析了诺兰达公司未来将面临的新挑战。
Borehole blasting is a basic process in the mining operations cycle and accounts for a large share of mining costs. Problems caused by improper drilling and blasting operations can result in millions of dollars in losses each year. Because of this, Noranda Technology Center (NTC) in 1984 started a blasting technology research program. The new progress made by Nolander Technology Center in drilling and blasting technology is summarized. In terms of ore loss and depletion, the impact of borehole blasting on Nolander Company is described. Finally, it analyzes the new challenges Nuolande will face in the future.
