我队308机在58年12月份在平均孔深350公尺,最深400公尺的深孔作业突破了千公尺关,实际进尺1200公尺,这給右傾保守及强調鑽孔深淺、岩石好鑽、設备好等条件論者一个有力的回击,为59年鑽探工程更大的跃进,在深孔鑽进創造高台月效率开辟了新的途徑。308机深孔鑽进能突破千公尺的主要經驗有如下几个方面。一、政治掛帥、解放思想、破除迷信 308机自58年4月份起曾几次掀起向千米进軍的高潮,但始終没有获胜,其主要原因是机台部份同志思想沒有彻底解放,認为本机台与302机不同,孔深,岩石硬,难打千米,且对小口徑鑽进有怀疑,怕出事故而不願採用。对深孔鑽进实現千公尺缺乏信心,碰到硬岩便灰心丧气,以致月初工作松懈,月底
Our team 308 machine in December 58 in the average hole depth of 350 meters, the deepest 400 meters deep hole operation exceeded the 1000 meters off, the actual footage of 1,200 meters, which gives the right conservative and emphasizes the depth of drilling, rock Good drilling, good equipment and other conditions of a powerful counterattack, 59 years of drilling more leaps and bounds, in the deep hole drilling to create a high efficiency of Taiwan opened up a new avenue. 308 machine deep hole drilling can break the main experience of thousands of feet in the following aspects. First, the political command, emancipating the mind, get rid of superstition 308 machine since April 58 has been set off from march to march the climax, but has never won, the main reason is the machine part of the gay thought is not completely liberated, The machine is different from the 302 machine, deep hole, hard rock, difficult to hit kilometers, and there is suspicion of small-diameter drilling, afraid of accidents and unwilling to adopt. Lack of confidence in deep hole drilling to achieve a thousand meters, met the hard rock will be discouraged, resulting in loose work early in the month
