近二十五年来,凿岩技术已从手提式凿岩机发展到六十年代初的第一台手控气动机械式凿岩台车,继而到七十年代的第一台液压机械式凿岩台车。下一步将是当今的电子计算机技术用于现代凿岩台车上的时代。采用液压凿岩技术以实现自动化过程比
In the past twenty-five years, rock drilling technology has been developed from portable rock drill to the first hand-controlled pneumatic rock drilling rig in the early 1960s and then to the first hydraulic rock drilling rig in the seventies . The next step will be the era of today’s computerized technology used in modern rock drilling rigs. Hydraulic drilling technology is used to automate the process
