去年以来，我们通过总结过去的经验教训，认识到要提高金刚石钻进的技术经济效果，必须提高金刚石钻头的使用效果。从四月份起，着重抓了提高金刚石钻头使用寿命这个关键问题，由于领导重视、全体钻探职工的共同努力，并制定了一些措施和管理办法，经过几个月的工作，取得了一定的效果。 Since last year, we have summed up the lessons learned from the past and realized that to improve the technical and economic effects of diamond drilling, the use of diamond bits must be improved. Since April, we have focused on the key issue of improving the service life of diamond drill bits. Due to the leadership’s attention, all the staff of the mine have worked hard and formulated some measures and management measures. After several months of work, they have achieved some results.
