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。
利用錨拉式地下連續牆技術對富水砂卵石層的露天礦邊坡加固後，如何控製爆破以確保邊坡穩定是值得深入研究的問題。本文以神龍峽露天礦為揹景，研究瞭最大一段裝藥量問題以及爆破後對加固後露天礦邊坡穩定性的影響。鑑測結果顯示，在閤理單響炸藥量爆破時，爆破對邊坡穩定性影響很小。

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 effect of blasting on the stability of reinforced slope are studied .The monitoring results show that the effect of blasting on the stability of slope is very little in a reasonable amount of maximum single fire dynamite .
