天水燎原风动工具厂、天水风动工具研究所和西安交通大学金属材料及强度研究室,为贯彻伟大领袖毛主席“开发矿业”的指示,制造高质量的风动工具,支援矿山建设,于1973年组成厂、所、校三结合钎尾攻关试验小组,针对 YG-80型导轨式重型凿岩机开展了提高钎尾使用寿命的研究,并在南京梅山铁矿进行了作业试验。目前,第一阶段试验已基本结束,取得了较好的效果。
Tianshui Liaoyuan Fengdonggongju, Tianshui Fengdonggongju Institute and Xi’an Jiaotong University Metal Materials and Strength Laboratory, in order to carry out the great leader Chairman Mao’s “development of mining” instructions, manufacturing high-quality wind tools to support the construction of mines, at In 1973, it formed the factory, the institute and the school combined with the experimental team of tailing attack research to carry out the research on improving the service life of the shank tailings for the YG-80 heavy rail rock drill. The operation test was carried out at the Nanjing Meishan Iron Mine. At present, the first phase of the test has basically ended, and achieved good results.
