结合楚大公路西洱河电站控爆工程 ,应用药壶控制爆破的扩壶工艺和减弱松动爆破原理 ,提出了“多次扩裂控制爆破”新工艺。介绍了该工艺在控制爆破飞石、减轻爆破震动等方面获得的效果 ,对复杂环境下的工程爆破有重要的参考价值 Combined with the control explosion project of Xi’erhe Hydropower Station on Chu-Da Highway, the new technology of “multiple-expansion controlled blasting” was put forward by using the expanding pot process controlled by the pot and the principle of loosening blasting. The effect of this process on controlling flying stone and reducing blasting vibration is introduced, which has important reference value for engineering blasting in complex environment
