边坡加固后露天采场的控制爆破研究

利用锚拉式地下连续墙技术对富水砂卵石层的露天矿边坡加固后,如何控制爆破以确保边坡稳定是值得深入研究的问题。本文以神龙峡露天矿为背景,研究了最大一段装药量问题以及爆破后对加固后露天矿边坡稳定性的影响。监测结果显示,在合理单响炸药量爆破时,爆破对边坡稳定性影响很小。

Study on the controlled blasting ofopen pit with reinforced slope

By the prestressed and pulled diaphragm wall technology, an open pit slope in the water-containing stratum of gravel and pebbles was reinforced, and how to control the blasting to ensure the stability of slope is worthy of further study.In this paper, taking Shenglongxia open-pit mine as the background, the maxium one-stage charge and effecet of blasting on the stability of reinforced slope are studied. The monitoring results show that, in a reasonable amount of maximum single fire dynamite,the effect of blasting on the stability of slope is very little.
