Abstract
Controlled tunnel blasting by deck charge was suggested and simulated by PFC and FEM analyses. Analyzed results showed that suggested method is efficient in fragmentation and able to decrease in vibration level because of decreased amount of charge per delay and dispersion of deck charge. This phenomena was explained by failure mechanism and proved that it can be successfully applied to tunnel blasting.
