Exploration Core Drilling Rigs Light Weight Mobile Drilling Rig 200m Core Sample Drilling Rig

200-Meter Deep Tunnel Exploration Core Drilling Rig
The 200-meter deep tunnel exploration core drilling rig is a specialized machine designed for underground geological investigation in tunnels, caverns, and confined excavation environments. Capable of reaching depths of up to 200 meters, this rig is essential for tunnel geological forecasting, rock mass classification, fault zone detection, and lining integrity assessment. Its compact and low-profile structure allows easy movement and operation within narrow tunnel cross-sections, while its modular components facilitate quick assembly and disassembly at restricted job sites. Equipped with a high-torque rotary head, precise hydraulic feed system, and wireline coring technology, the rig delivers high core recovery rates with minimal sample disturbance even in hard or fractured rock formations. Advanced dust suppression and noise reduction features make it suitable for tunnel environments where air quality and noise control are critical. The rig also supports real-time monitoring of drilling parameters, ensuring safe and efficient operation. Durable, reliable, and specifically engineered for underground use, this tunnel core drilling rig is the ideal tool for obtaining accurate geological data in deep tunnel projects.
