一、小麻面爆破麻面爆破的目的,是将坡体内部引起滑坡的滑面崩成凸凹不平的麻面以增加滑面摩擦力,提高边坡的稳定性。麻面爆破与普通工程爆破的对比参见图1。麻面爆破又分为大麻面爆破和小麻面爆破。它们的区别如下:只将滑面崩碎,使滑面上下的滑体和滑床有轻微破坏的爆破为小麻面爆破(图1c);不仅将滑面崩碎,而且还将滑面下的部分滑床及滑面上的全部滑体一
First, the small face blast blasting Ma face blasting purpose is to slide the landslide slippery surface caused by smooth collapse into uneven surface to increase the sliding friction and improve the stability of the slope. Comparison between ordinary blasting and normal blasting see Figure 1. Ma face blasting is divided into cannabis blasting and small ma face blasting. The difference between them is as follows: Only the sliding surface is broken, so that the blasting body with slight damage to the sliding body and sliding bed above and below the sliding surface is a small surface explosion (Figure 1c); not only the sliding surface is broken down but also the sliding surface Part of the slide and sliding surface of all the slide one
