Directional coring technology is not only applied to determine ore layer and texture plane occurrence, but also used to identify ore layer distribution, understand the formation trend and predict bending trend of the borehole. The paper introduced the principle of core-storage directional core drilling, the key techniques, instrument constitution, technical parameters and the site application.
