地下爆破漏斗实验方法研究

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。

Blasting Crater Experimental Methods for Underground Blasting

Blasting crater experiment is an efficient method to obtain blasting parameters. It is also an important basis of blasting design and operation. After developing for many years, C.W.Livingston law for blasting crater is a general guideline of blasting crater experiments. It is usually to drilling some vertical blasting holes in the level ground when blasting crater experiments are conducted. Then, the blasting crater experiments can be done with designing parameters. But the classical blasting crater experiments can not be carried out in underground blasting such as horizontal hole, up hole and Vertical Crater Retreat blasting except for bench blasting. The blasting mentioned above are usually used in underground mines and tunnels. In order to provide functional blasting crater experimental methods for underground blasting, the basic principle of it was studied. Beyond, the types, procedure, measurement and analysis methods of underground blasting crater were also offered. The methods are beneficial for underground blasting.
