摘要
文章介绍了通过对爆破参数的计算选取,以及采取地表柔性覆盖方法,取得了对飞石的控制效果;通过施钻减震孔、减小单响药量等措施,消减爆破产生的地震效应,取得对邻近大体积混凝土的保护效果。
The paper achieves the control effect of flying rock through calculation and selection of blasting parameters and using surface flexible cover method,gets protection effect to neighbor mass concrete through the decreasing earthquake effect caused by blasting using these measures such as drilling shock relieve vent and decreasing the powder in a single hole.
