摘要
本文简述了多排同段爆破技术在狮子山铜矿的应用情况,以及它的应用条件与规律,分析了岩石爆破过程中的破碎机理,探讨了原生的和再生的节理裂隙对岩石破碎的重要影响及多排同段爆破过程中裂隙发展的特色;指出了集能效应的存在规律及其在多排同段爆破技术中的作用;最后客观地评价了这一爆破技术的应用前景。
Multiple-row same fired blasting technique, which is adopted in Shizi-shan Copper Mine, is described, including its basic rules and application conditions. The rock-breaking mechanism, the significant influences of primary and secondary jointed fissures on rock fragmentation and the developmental features of rock fissures during the blasting process are also discussed. The paper then points out the basic rules of energy-focusing effect and its role in multiple-row one deck blasting. Finally, the future of this blasting technique is evaluated objectively.
