47mm Friction Bolt and Split Set is mainly used as primary support in mechanized jumbo development and production mining.
It is one of the standard Friction Bolt and Split sets widely used in worldwide projects of mining, tunnels, and dams as rock support material.
Different thicknesses are available, such as 3.0mm, 3.2mm
Both galvanizing and black are available.
The 47mm friction bolt split set stabilizer is a type of ground support tool commonly used in mining, tunneling, and other geotechnical applications to stabilize rock and soil.
Diameter: 47mm (approximately 1.85 inches)
Material: High-strength steel, often with a galvanized or coated finish to resist corrosion.
Length: Available in various lengths, typically ranging from 1.2 meters (4 feet) to 3.6 meters (12 feet), depending on the application.
Design: A tube-like structure with a slot along its length that allows it to compress when driven into a hole, creating friction against the rock surface.
Installation: Easily installed using a jumbo or handheld drill rig, often with a driving cap to protect the bolt during installation.
Accessories: Often used in conjunction with bearing plates and domed plates to distribute the load and provide additional support.
