摘要(Abstract)：
本文介绍了丹江口水利枢纽自备防汛电厂基础石方开挖控制爆破施工及爆破安全监测的全过程，重点介绍了爆破振动监测、原型对比性观测等。观测结果表明：在大坝坝址附近进行基础石方开挖的控制爆破是成功的，爆破对丹江口大坝安全没有不良影响，施工期间大坝运行正常。
The paper covers the whole process from blasting control of foundation earthrock excavation to blasting safety supervision,especially the supervision of the blasting vibration and the comparative observation to the original state.The supervisory data shows that the control balsting is successfully used in the foundation earthrock excavation near the dam.It has no any harmful influence on the safety of Danjiangkou Dam and the dam operated normally during the construction.
