In underground mineral exploration, tunneldrills act as pioneers, fetching geological data in narrow spaces. Tunnel drilling applies surface techniques underground for varied goals: mapping rock structures, detecting water/gas risks, and finding hidden ore bodies.
It requires small, automated drills to cut costs in tight tunnels. Rigs must drill at any angle; holes start in bedrock with simple structures. Exploration uses 46/59mm diameters; coal mines use larger 75/91mm ones.
Power comes from electric-hydraulic motors or air. Gear needs water/dust/fire/explosion protection. Faster than tunnel excavation (up to 10x quicker) and cheaper, it’s vital for mining, driving industry progress.
