| Abstract: | Micro-difference blasting in deep hole is carried out in excavation of diversion tunnel at Dahekou hydropower station. By analyzing and comparing checking computation and measurements,adquate blasting method,parameters for drilling and blasting and blasting range are obtained. This plays a imPOrtant role to speed up construction progress and gains obvious economic and social benefit. |
