Tunnel Core Drilling Rig
A tunnel core drilling rig is a specialized mechanical equipment designed for extracting cylindrical rock or soil samples (cores) from tunnel walls or surrounding geological formations during excavation or geological surveys. It features a high-precision rotary drilling mechanism equipped with diamond or carbide-tipped drill bits capable of penetrating hard rock layers. The rig is typically mounted on a stable, adjustable frame to ensure vertical/horizontal alignment and minimize vibration in confined tunnel environments. Integrated hydraulic or electric power systems provide controlled drilling speed and torque, while core retention technology preserves sample integrity for structural analysis. Its compact design allows operation in limited spaces, with dust/water cooling systems to suppress airborne particles. Essential for assessing rock strength, fracture patterns, and groundwater conditions, it ensures safety and informs reinforcement strategies in tunnel engineering projects.
Hydraulic underground core drilling rig is suitable fro drilling holes for the purpose of mine exploring,also they could be used in surface coring,railway engineering,tunneling,
construction and water conservancy project.
Is designed especially for underground 360°drilling work,to drill holes in the tunnel. capable of diamond core drilling and other drilling works.

Features:
1.The sliding and extending & retracting function of the mast makes it convenient for the bottom of mast to touches the ground or platform, thus the drill rig will be more stable.
2.The swinging arm and mast can do luffing movement, which satisfy the request of multi-angle drilling.
3.The core drilling machine system of oatation,feed,pumping and clamping relies on fluid drive.
4.Under bad transportation condition, the main frame also can be disassembled ,easy to transport.
5.It is light weight, small size, easy operation, with good performance, simple structure and easy to maintain.
