| Abstract: | According to the special geological conditions of the big difference in the surrounding rock cat- egories in Meng Yejiang hydropower station＇ s tunnel, the paper took the measure of engineering analogy and site test, and proposes tunnel-controlled blasting parameters, blast hole layout, explosive loading structure, priming circuit, construction schemes and resolution in the complex geological conditions of tunnel excavation blasting. The result shows that as long as the correct choice of blasting parameters and reasonable construction methods, the cavern excavation in complex geological conditions can achieve a good blasting effect. |
