钻探工程的基本目的在于采取地下标本(岩心),藉以研究勘探地区的地质构造,并作出对某矿区的储量计算。因此,钻探工作中采取岩心的好坏多寡,就直接影响到对一个矿区估价的确切性,特别是深部盲矿体的饰置与岩心采取情况有着极密切的关系。这是钻探工作者所必须明确的。岩心无论在数量上(岩心采取的百分率)或质量上,都应当满足地质人员提出的要求。采取岩心是一件重要而复杂的事情。技长不仅要有丰
The basic purpose of the drilling project is to take underground specimens (cores) to study the geological structure of the exploration area and to make reserves calculations for a certain mining area. Therefore, the exact amount of core that is taken during the drilling work directly affects the accuracy of the valuation of a mining area. In particular, the installation of deep blind ore bodies is closely related to the situation of core collection. This must be clear to the drilling worker. The cores should meet the requirements of the geologists both in terms of their number (percentage of cores taken) and their mass. Taking a core is an important and complicated thing.
