This invention discloses a fixed-point pressure-maintaining coring device for deep directional long boreholes in coal mines. It mainly utilizes the sliding of a sliding column within the casing, and the top plate can dynamically adjust its radial position according to the actual diameter of the core. Even if the core has local irregularities, it can maintain uniform contact force, preventing the core from falling off or breaking during drilling. Furthermore, the rounded corners at the bottom of the top plate and the slightly larger diameter of the coring opening formed by the enclosure ensure that the core can smoothly enter the storage chamber, reducing entry resistance and mechanical damage, and protecting the integrity and original structure of the core, providing high-quality samples for subsequent geological analysis.
