The observation result of vibration is rational either in middle shallowblasting or in rock excavation near the dam.
不论是中部浅孔爆破，还是大坝近区岩体开挖，其振动观测结果总体合理。
2
The design and implementation of shallow hole smooth blasting and springing blasting in complicated circumstances are introduced on the basis of field test.
结合工程实践，介绍在复杂条件下，进行浅眼光面爆破与药壶控制爆破相接合的设计与施工经验。
3
The effective measures to control the vibration and fly rocks were adopted to successfully perform the application of large hole in shallow hole controlled blasting.
