【摘要】：爆破漏斗实验是获取岩体爆破准确参数的有效途径,是爆破设计和施工的重要基础。经过多年的发展,利文斯顿爆破漏斗理论成为指导爆破漏斗实验的普遍规律。爆破漏斗一般是在水平地面向下打垂直孔,然后按照设计参数进行装药实验。对于地下矿山或隧道爆破,除台阶爆破可以采用垂直孔进行经典的爆破漏斗实验外,水平孔爆破、上向孔爆破和VCR法爆破都不宜使用标准的爆破漏斗实验方法。为此,本文全面总结爆破漏斗实验的基本原理,研究了地下爆破漏斗的类型、实验步骤、参数的测量方法、实验结果的分析方法,为地下爆破漏斗实验研究提供了有益的参考。
[Abstract]:Blasting funnel experiment is an effective way to obtain accurate blasting parameters of rock mass and an important foundation for blasting design and construction. Livingston's theory of blasting funnel has become a general rule for guiding blasting funnel experiments. Blasting funnel is generally used to drill down vertical holes in horizontal ground, then charge experiments are carried out according to design parameters. For underground mine or tunnel blasting, Except for the classical blasting funnel experiment with vertical hole, horizontal hole blasting, upward hole blasting and VCR blasting are not suitable for the use of standard blasting funnel test methods. In this paper, the basic principle of blasting funnel experiment is summarized, and the types of underground blasting funnel, experimental steps, measurement method of parameters and analysis method of experimental results are studied, which provides a useful reference for the experimental study of underground blasting funnel.
