In order to further implement the teachings of Chairman Mao Zedong, the great leader and mentor, under the guidance of wise decision of Chairman Hua in guiding the country’s rule of governance, according to the requirements of mines and instructions from higher authorities, after conducting in-depth mine surveys on site, Work, I plant in 76 years for the double-boring trolley developed YGP28 rail-type high-frequency rock drill. At the beginning of 1977, the industrial tests were carried out in the Taolin lead-zinc mine in Hunan Province and the Shirenguan tungsten mine in Guangdong Province, respectively. The expected results were achieved and the targets specified in the technical mission statement were met. In June 77, a ministry and ministry of metallurgy, metallurgy, chemical, coal, two aircraft and a machine system of mines, research institutes, institutions of higher learning and manufacturing representatives held appraisal meeting, passed the appraisal, is about to put into mass production. Figure 1 shows the appearance of YGP28 high-frequency rock drill. Figure 2 is its structure.
