摘要
通过对白云铁矿主采场不同矿岩性质和结构构造的分析研究进行孔网参数的优化,在确保爆破质量稳定的前提下使延米爆破量逐年提高,降低了穿孔费用,对降本增效发挥了重要的作用。
Through the analysis and research for various rock properties and structures with Baiyunrbo iron ore main stope, we can optimize the parameters of hole distribution. Under the condition of ensuring the stable blasting qualities, we improved blasting output per meter hole by year. Therefore, it reduced the perforation costs and played an important role in reduction and efficiency.
