摘要
为了解决目前国内外超硬全岩巷掘进存在的进尺慢、安全性差、效益低等问题,采用超高压水力破岩技术和液压冲击破岩技术进行超硬岩破碎。在简要阐述超高压水力破岩技术和液压冲击破岩技术的典型结构和原理之后,对2种破岩技术的可实施性进行了分析和计算。
In order to solve the problem of slow excavation speed, poor security performance and benefit in super-hard rock roadway at home and abroad,feasibility of super high hydraulic pressure rock broking and hydraulic impact rock broking technology are studied in aspect of super hard rock crushing. After stating the typical structure and principles of two kinds of rock broking technology,the feasibility of implementation is analyzed and calculated for two kinds of rock broking technology.
