复杂环境大区露天深孔台阶爆破技术在岙山油库区开挖中的应用

摘要

介绍了复杂环境下大区深孔台阶运孔毫秒延时爆破技术在岙山油库区开挖中的应用.认为采用正方形布孔方式、适当加大炸药单耗和钻孔超深、采用高精度雷管起爆、起爆顺序应结合爆区形状和岩层结构情况以及振动监测等是成功实施复杂环境下大区深孔台阶逐孔毫秒延时爆破设计的重点内容.%The application of large deep hole bench blasting with millisecond delay hole by hole was introduced in complex environment in aoshan oil reservoir excavation. It is important for designer to arrange blast hole by square, increase specific charge and over - depth of blast hole properly, high - precision detonator, and the firing order based on the shape of blast area and the rock stratum and the monitoring of blasting vibration.
