提高岩、矿心采取率是获得岩、矿层第一手实物資料的重要关鍵。在钻探工程的实践中,常常可以看到这样的現象:就是,經过努力从数字上看,采取率虽然滿足了质量指标的要求,但是由于种种原因,使岩、矿心結构被損坏,矿心成分被污染,大大降低了岩、矿心的代表性,以致在岩、矿心品质上并未完全滿足地质要求。这一現象应引起钻探工作者的密切注意。我們必須在提高采取率的基础上,进一步提高岩、矿心的品质,逐步做到尽可能地取得与原状相接近的岩、
Raising the rate of rock and core collection is the key to obtaining first-hand physical data of rock and ore layers. In the drilling engineering practice, we can often see the phenomenon: that is, through the efforts of figures from the point of view, although the adoption rate to meet the quality requirements of the index, but for various reasons, so that rock and core structure is damaged, Core composition is contaminated, greatly reducing the rock, mineral core representation, so that rock, ore quality does not fully meet the geological requirements. This phenomenon should arouse the close attention of drilling workers. We must, on the basis of improving the adoption rate, further improve the quality of rock and mineral core and gradually make it possible to obtain the rock as close as it is possible,
