夹皮沟矿自1951年以来,使用中空钎子的岩机已全部执行了湿式岩,在劳动保护与提高效率上都曾收到显著成绩;但在采矿与采准作业上,因下戏台坑矿床为缓倾斜,走向与倾斜变动频繁,试用其他机器未成,加以ТП—4型岩机又少,所以仍旧使用 CC—11型岩机,实心钎子没有通水路,一直认为无法进行湿式岩。至今年第二季度讨论生产任务时,在领导上动员群众发挥智慧,改进 CC—11型岩机岩条件的号召下,生产科许墨林同志提出用
Jiapigou Mine Since 1951, rock drills using hollow brazing rods have all been implemented with wet rock and have received remarkable achievements in labor protection and efficiency improvement. However, in mining and quarrying operations, The deposits are gently inclined, and the trend and inclination are frequently changed. When the other machines were not tested, the number of ТП-4 type rock machines was small. Therefore, CC-11 type rock machines were still used, and solid brazing stones did not pass through the waterways. At the time of discussing production tasks in the second quarter of this year, he called for the leadership to mobilize the wisdom of the masses and improve the rock conditions of the CC-11 rock.
