Implication

Field test reveals optimized charging parameters reduce rock damage in diversion tunnels, indicating improved construction safety for hydraulic tunnel excavation.

Key Points

Reducing explosive charges in cut holes while increasing perimeter hole charges minimizes rock mass damage, curbing unwanted tunnel deformation.
Field test monitoring of two charging methods evaluates blast disturbances using multiple techniques, including wave velocity and microseismic tests.
Highlights safer excavation schemes for hydraulic tunnels, offering a multi-technique framework to optimize blasting parameters in underground works.
