摘要(Abstract):
大型铜块体尺寸大、韧性好,其他方法很难拆分,因此只能采用爆破法将其切割。本次实践根据聚能药包原理,采用不同尺寸的线性聚能药包,对不同厚度的铜块体进行切割。通过合理选取爆破参数,采取导爆索起爆网路,应用覆盖和近体防护等安全措施,有效地阻止了飞块和空气冲击波产生的危害,最终达到了预期的爆破切割效果。
Owing to their large size and toughness,the copper blocks were hard to cut by using other common methods,and therefore,the explosion cutting has to be adopted.The present cutting practice was based on the principle of energy-concentrated charge,using linear-shaped charges of different sizes to cut copper blocks with different thickness.Though selecting the reasonable blasting parameters,employing fuse ignition network and using cover and the safety protection measures,namely,covering protection,indirect protection and conservative protection,the danger of flying rock has been effectively prevented,and as a result,the practice reached its reached the desired blasting cutting results.
