摘要
结合新建赣州至韶关铁路黄竹头隧道工程,通过深入调查研究并总结其板岩结构的地质特性、阐述了针对不同的板岩结构,如何通过正确的爆眼设计和爆破技术获得较好的爆破效果,减少对软弱围岩的扰动和硬质围岩中遗留岩体的损伤。
Combined with Huangzhutou Tunnel engineering of Ganzhou to Shaoguan railway,through investigating and summarizing its slate structure geological characteristic,it was described that how to adopt correct blasting eyes design and blasting technology to get good blasting effect in different slate structures,and then to reduce the disturbance of weak rock and the damage of left hard rock.The results can provide reference to similar tunnel construction.
