在钻探现场,应把钻取的岩心进行清洗、编号、加牌、按顺序摆放在岩心箱中。随后,写好箱号和箱的回次号等。任何一个环节出现错误,都会影响地质资料的准确性。据笔者在现场的观察,最容易发生的错误就是岩心倒置。近年来,由于新工人比例增加,这种现象有增无减。岩心倒置的主要原因是: 1.现场记录员和班长责任心不强。①清洗岩心时,把岩心一次全部倒入水桶中,造成岩心混乱;②从岩心管中敲出岩心时,将钻具吊悬的角度过陡、造成岩心一次涌出,使岩心混乱;③从岩心管里取出的岩心顺次正确,但由于几个人同时动手向岩心箱摆放,使岩心发生倒置。 2.置于岩心箱中的岩心,本应把先进入岩心管的岩心摆在前头,使本回次的岩心与上回次的最后一块岩心相 At the drilling site, the drilled cores should be cleaned, numbered, added, and placed in order in the core box. Then, write the box number and box number and so on. Any link errors, will affect the accuracy of geological data. According to the author in the field of observation, the most prone to error is rock core inversion. In recent years, this phenomenon has been steadily rising as the proportion of new workers has increased. Core inversion is the main reason: 1. Field recorder and monitor responsibility is not strong. ① When cleaning the core, the core is poured into the bucket all at once, causing the core to be disrupted. ② When the core is knocked out from the core tube, the angle of the drilling tool is too steep, causing the core to gush once and cause the core to be disrupted. Core out of the core tube in the correct order, but because several people at the same time hands placed on the core box, so that core inversion. 2. The core placed in the core box should have put the core first entering the core tube in the foreground so that the core of the current backcrossing is the last core phase
