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.
