一、概述双向继爆管是多排微差爆破的重要起爆器材之一;本文介绍的是双向继爆管-导爆索起爆网路在离构筑物很近的多排水平深孔爆破工程中的应用。我所曾协助有关单位进行了两次船坞坞口炸礁工程。第一次是小坞口爆破,爆破药量为梯恩梯3000多公斤,爆破的岩方量为5800多米~3;第二次是大坞口爆破,爆破药量为梯恩梯6200多公斤,爆破的岩方量为12000多米~3。
First, an overview of two-way tube is one of the most important two-way burst blasting equipment; This article describes the two-way following the tube - detonating cord detonation network close to the structure of the multi-row horizontal deep-hole blasting project application. I have assisted the relevant units in carrying out two reef reef projects at the dock. The first is a small dock blasting blasting dose TNT more than 3000 kilograms, blasting rock mass is more than 5800 meters ~ 3; the second is a large dock mouth blasting blasting dose TNT more than 6200 kilograms, blasting rock The amount of more than 12,000 meters ~ 3.
