我队二分队今年接受了用水平钻探代替平洞对永登大闸子石灰岩矿进行勘探的任务。分队技术力量薄弱,90%为新手,在批林批孔运动中,坚持实践出真知的辩证唯物史观,高举总路线和“鞍钢宪法”的旗帜,在兄弟单位的支援下,全队职工团结战斗,克服重重困难,用4天时间打完了74.91米的水平钻孔后,及时总结经验,吸取教训,再接再励,又用23天和18天时间打完了374.45米和40.24米的两个水平钻孔。台效490～670米/台月,矿心采取率分别达88.7%和93%,
This year our Second Detachment accepted the task of prospecting the Yongdeng Paragon limestone mine by using horizontal drilling instead of Pingtung this year. The detachment is weak in technology and 90% is a novice. In the campaign to criticize Lin and Pidai, he persisted in practicing the dialectical materialist concept of history and held high the general line and the banner of “Ansang Steel Constitution.” With the support of his brother unit, , Overcame numerous difficulties.
