我队九号机自从76年开始金刚石钻进以来，全机人员认真学习金刚石钻进技术，从实践中不断总结经验，逐步提高操作技术水平，大大提高了铜山口矿区的钻探效率，降低了钻探成本，连年提前完成国家计划，充分发挥了金刚石小口径钻探的优越性。在钻头使用上，七七年使用无锡天然孕镶7005~#钻头，创造了单个钻头进尺403.97米的我队最高纪录；七八年使用郑州天然表镶2588~#钻头，单个钻头进尺高达442.63米；七九年使用郑州天然表镶2990~#钻头，创造了单个钻头进尺502.73米的新纪录。
Since our team began drilling diamonds in 1996, our crew has conscientiously studied the diamond drilling technology. From experience, we continuously sum up our experience and gradually improve our operational skills. This has greatly enhanced the drilling efficiency in the Tongshankou mining area and reduced the drilling Cost, year after year to complete the national plan, give full play to the advantages of small-diameter diamond drilling. In the use of drill bits, the use of natural pregnant impregnable set 7005 ~ # bits in Wuxi in the past seven or seven years, creating the highest record of 403.97 meters for a single drill in our team. In 1978, Zhengzhou natural watch set 2588 ~ # drill bits were used, with the single drill footage up to 442.63 meters In 1979, Zhengzhou natural watch set 2990 ~ # bit was used, creating a new record of 502.73 meters for a single bit.
