在复杂地层小口径金刚石钻进(包括绳索取芯)过程中所遇到的问题,比大口径钻进更复杂、更难处理.因此,认真总结经验,研究其综合治理方法,是一个很重要的问题. 我们从1976年开始推广小口径金刚石钻进,目前开动10台金刚石钻机(包括两台绳索取芯钻机).施工的矿区大部分是复杂岩层,为了解决生产实践中的问题,我们组织了经常性的技术攻关,摸索了一些综合治理的措施,使生产效率有了较大幅度的提高,特别是在四方山、金斗矿区分别完成了普通小口径最深钻孔925米和绳索取芯最深钻孔782米.1982年优质孔率为97%,单位成本显著下降.西岔矿区的八号机,孔孔优质,台
Problems encountered during drilling of small diameter diamonds (including rope coring) in complex formations are more complex and difficult to handle than large borehole drilling, so it is important to carefully summarize experience and study its integrated approach We started to promote small diameter diamond drilling since 1976. Currently, there are 10 diamond drilling rigs (including two rope core drilling rigs), most of which are complex rock formations. In order to solve the problems in production practice, we organize The regular technical research, to explore some of the measures to comprehensively control, so that the production efficiency has been greatly improved, especially in the Quartet Hill, Jin Dou mining area were completed the most common small diameter drill 925 meters and the core rope The deepest hole 782 meters .1982 high-quality hole rate of 97%, the unit cost dropped significantly.Xiecha mining area on the 8th machine, hole quality, Taiwan
