BOLTER 99

Structure and operating principle

• • Structure: BOLTER 99 usually includes the following main parts:

    • Frame: As the main load-bearing part, it is solidly designed to withstand impacts during operation.
    • Handpiece: Equipped with specialized drill bits to drill holes into the basement roof.
    • Pneumatic hammer: Use compressed air to drive screws into drilled holes.
    • Grid system: Provide steel mesh for dividing tunnel roof mesh.
    • Control system: Control machine operations such as drilling, screwing, and mesh tensioning.

  • Working principle:

    1. Drilling holes: The machine will drill holes into the basement roof at the specified distance and depth.
    2. Screw closing: Once drilling is complete, the pneumatic hammer will drive screws into the drilled holes.
    3. Meshing: The steel mesh is stretched and fixed to the screws to form a protective mesh layer for the tunnel roof.

Advantages of BOLTER 99

• Enhanced safety: Helps increase the durability of the basement roof, minimizing the risk of collapse and landslides.
• Improve work efficiency: Replace manual labor, increase productivity.
• Quality Assurance: Screw and stretch the mesh evenly and accurately, ensuring the quality of the project.
• Flexible: Can be adjusted to suit different geology and mine sizes.

Application

BOLTER 99 is widely used in mining operations, especially in underground mines. Specific applications include:

• Screwing and roof meshing: To increase the durability of the basement roof, prevent collapse and landslides.
• Construction of underground works: Used in tunnel construction, underground hydroelectric projects.
• Mine repair and maintenance: Used to repair damaged basement roof sections.
