摘要:
为提高冻土爆破效率，采用新型聚能爆破穿孔技术，利用专业爆破软件对冻土进行爆破穿孔数值模拟，结合冻土聚能穿孔和爆破试验验证，研究解决冻土穿孔和抛土爆破的关键技术难题。验证结果表明：数值模拟能取得聚能爆破的近似结果，使用球缺形及新型材料制作的聚能穿孔器有利于对冻土的侵彻，形成的直筒形爆破孔能够满足装药爆破、特别是串联随进型装药爆破的要求，而且可通过变换炸高适当调整穿孔深度，在接近于冻土和非冻土界面处装药爆破可取得更有利的爆坑形状。
Abstract:
A new shaped charge blasting perforation technique was used to improve the blasting efficiency on frozen soil. Professional blasting software was used to simulate the blasting perforation for frozen soil. Shaped charge perforation of frozen soil and blasting test verification were combined to solve the key technical problems of frozen soil perforation and soilcasting blast. Experiments show that numerical simulation results are similar to that of test. Hemispherical shaped charge perforator made by new materials is good for the penetration to frozen soil, and the straight blast holes could meet the demand of charging,in particular,the tandem charging. The perforation depth could be adjusted by changing the blasting height. Charging near the interface of frozen soil and soil could get the better shape of blasting holes.
