| Abstract: | A bulk mass blasting project,the open cut of the mouth of No. 1a ventilating tunnel in the primary pumping station of the YRDP is introduced from blasting design,determination of standard of blasting vibraion,optimization of blasting parameters,construction of controlled blasting to the computation of safe velocity of vibration in course of blasting. The chip and bench blasting,presplit blasting,deep hole blasting,excavation of drain ditch and determination, connection and preservation of the blasting network adopted in the blasting construction are mainly illustrated.The blasting result shows that the bulk mass controlled blasting project for open cut near densely populated residential area is successful,the blasting has no influence on nearby facilities and buildings,all the facilities in construction period run normally.The blasting project was completed in January,1998,and about 26 000m 3 of rock had been cut within 45 days. |
