| Abstract: | Tunnels with three different kinds of fracture surface through karst area were taken as examples for study, blasting programs for them were proposed in terms of blastholes arrangement, explosive charge structure and detonating network, with key points in operation of drilling hole, charge filling and over-excavation and under-excavation control specially elaborated. On-site practice testified the proposed blasting program and operating method being reasonable for such tunnels through karst area with special sections, which can be taken as reference and guidance for the blasting operation in large karst area in the future. |
