摘要
利用Instantel振动监测仪对直角拐弯硬岩巷道中深孔爆破过程中的振速监测结果,分析并得出了切合现场实际的爆破损伤影响范围的PPV公式,并通过数理统计方法,反算最大单段安全装药量,经工程实践获得了较好的应用效果.
By means of Instantel Monitor the vibration velocity monitoring data are got when medium length or deep hole blasting takes place where hard rock tunneling advances rectangularly, and based on the data the PPV formula of blasting damage dimension is gained which is suitable to the real tunneling situation. The biggest safe charging weight of single section is Contra - calculated by the mathematical statistics method. The charging weight is put into engineering practice, and good result is achieved.
