摘要
某露天铜矿山工程地质、水文地质条件复杂,边坡岩性基本为泥质边坡及风化岩边坡,采区爆破采用的是中深孔爆破,爆破振动对采区固定边坡稳定性影响较大,目前采区各个方向边坡均有不同程度垮塌现象。本文主要探索采区爆破振动监测方法及监测数据分析方法,以在保证爆破效果的前提下,控制爆破振动,确保采区固定边坡稳固。
The engineering and hydrogeological conditions of an open-pit copper mine are complicated,the slope is basically muddy slope and weathered rock slope,and the blasting in the mining area is medium-deep hole blasting.The blasting vibration has a great influence on the stability of the fixed slope in the mining area.At present,the slope in all directions of the mining area has different degrees of collapse.This paper mainly explores the monitoring method of blasting vibration in mining area and the analysis method of monitoring data,so as to control blasting vibration and ensure the stability of fixed slope in mining area under the premise of ensuring blasting effect.
