| Abstract: | In excavation of underground workshop's rock anchor beam for Lashiwa Hydropower Station,the zoning and stepping excavation was used to protect area.The optimal excavation scheme and blasting parameters were determined through adjusting the inclination of smooth blasting holes,launching the field test by various plans,and proceeding the sonic test of rock destroy circle by blasting.The quality of formed rock benchis in agreement with design desire. |
