ZHAO Xiang,LIANG Kai-shui(School of Resource and Environment Engineering,Wuhan University of Technology,Wuhan 430070,China)  
In order to optimize blasting parameters and timbering measures,blasting vibration and wall rock distortion of underground factory building evoked by blasting excavation are monitored in the Storage Power Station of Bailian River.The general situation of monitoring and some data are introduced.These data are analyzed and compared to stipulate sound particle velocity and permissible value of wall rock.The engineering blasting parameters and timbering measures are suitable for this engineering.
