摘要
露天矿液压钻机近十年的主要进展有:配用规格系列齐全的高效重型液压凿岩机,采用管式钻杆使液压凿岩机进入大孔径领域,采用某些钻机辅助设施和液压控制系统,显著提高了钻孔效果,实现了斜孔钻进。
The new development of open-pit hydraulic drill ir recent ten years is summariezd. Employment of a series of highly efficient heavy-duty draulic drill and introduction of larg-er diameter tubular drill and auxiliary devices and hydraulic con-trio system in the drill have significantly improved the efficiency, bringing about inclined drill.
