A Tunnel Two-Boom Rock Drilling Rig is a type of heavy machinery commonly used in tunneling and underground excavation projects. It is designed for drilling into rock surfaces with precision and efficiency, typically for purposes such as creating blast holes or installing anchors. Below are its key features and components:

　　Key Features:

　　1. Dual-Boom System:

　　- Equipped with two booms, allowing simultaneous drilling at multiple points.

　　- Increases productivity and reduces the overall time required for drilling operations.

　　2. Articulated Arms:

　　- Highly flexible and capable of reaching various angles and heights within the tunnel.

　　- Ideal for irregular tunnel profiles or tight spaces.

　　3. Drilling Capacity:

　　- Can accommodate various rock conditions, including hard rock and fractured formations.

　　- Advanced rock drilling equipment, often with hydraulic or pneumatic systems.

　　4. Automation and Control:

　　- Many rigs are equipped with computerized controls for precision drilling.

　　- Automated functions, such as positioning and feed rate adjustments, improve accuracy and safety.

　　5. Robust Chassis:

　　- Mounted on a wheeled or tracked base for mobility in rugged underground environments.

　　- Designed for stability and ease of maneuvering.

　　6. Operator Cabin:

　　- Ergonomically designed and often air-conditioned for operator comfort.

　　- Enhanced visibility and control interfaces for effective operation.

　　7. Power Source:

　　- Typically powered by diesel engines or electric motors, depending on the project's requirements.

　　Advantages

　　- Improved Working Efficiency: The double - arm design allows for simultaneous drilling operations, reducing the working time.

　　- Reduced Labor Intensity: The automation functions reduce the difficulty and intensity of manual operation.

　　- Enhanced Drilling Quality: The automatic positioning and anti - jamming functions ensure the accuracy and stability of drilling.

　　- Increased Safety: The equipment is equipped with safety protection devices such as FOPS and ROPS protection, which improve the safety of operators.

　　Applications:

　　- Tunnel Construction: Used in mining, road construction, and hydropower projects.

　　- Underground Excavation: Ideal for creating underground spaces such as subways or storage caverns.

　　- Rock Stabilization: Drills holes for installing rock bolts or anchors to stabilize the surrounding rock.
