In geological exploration, core drill rig act as precise underground “scouts,” fetching rock samples. These samples provide key data for geological research and mineral exploration.
Core drills evolved with exploration tech: early mechanical models were slow; mid-20th century hydraulic upgrades boosted power. 21st-century smart features (remote control, auto logging) enhanced precision and efficiency.
Types vary by depth: shallow drills (<50m) for surface surveys; medium (50-500m) for mineral prospecting; deep drills (>1km) for large deposits and research. They aid ore analysis, tectonic studies, and engineering site selection, advancing toward deeper, more accurate drilling.
