摘要
在复杂地质条件下进行掘进施工,合理的钻爆方案对洞室围岩稳定、减少爆破震动引起周边岩体松动、确保施工安全有着重要的意义。乳化炸药在多裂隙围岩条件下的使用效果与硝胺炸药不同,施工中要限制最大用药量、毫秒延期控制爆破、改变装药结构、采用合理控制爆破技术,才能有效提高洞室幅员质量。
The reasonable drilling and blasting program for the tunnel construction under complicated geological conditions is the key for surrounding rock stability and construction safety. As the different construction effect of emulsion explosives to nitramine explosives for muhi-fraetured rock, limiting the maximum dosage, taking millisecond delay blasting, changing the charging structure and using reasonable control technique can effectively improve the quality of chamber when using emulsion explosives.
