手掘平巷爆破工作是一项比较复杂的工作。为了寻求一套比较切合实际的爆破方法,我们于六四年在陕一队进行了三个多月的试验,初步寻找出一些符合于手掘平巷实际情况的爆破参数。现将我们在工作中的一些体会介绍如下:
Hand driving tunnel blasting work is a more complicated job. In order to find a more realistic blasting method, we conducted a trial of more than three months in Sha-I in 2014 to find out some blasting parameters that are in line with the actual conditions of the excavation. Now we are some of the experience in the work described below:
