摘要(Abstract)：

介绍了渝长公路K31+4 2 5 - 6 80段路堑开挖深孔爆破的工程实例 ,论述了爆破方案的确定、爆破参数设计及主要的安全措施等。针对复杂的爆破环境 ,采用预裂爆破、加强堵塞和严格控制最大一段起爆药量等技术措施 ,保证了爆破安全 ,取得了预想的爆破效果。
In this paper, an engineering example of deep hole controlled blasting in cutting excavation of K31+425-680 section of Chongqing to Changshou Highway is introduced and the determination of blasting scheme, the design of blasting parameters, main safety precautions and others are expounded. For complicated environment conditions, a series of technological measures such as pre splitting, strengthened stemming and strict control of maximal charge per delayed interval are adopted, thus achieving blasting safety and predicted blasting results.
