MF33 Hot Dip Galvanizing Friction Bolts Underground Gold Mine Support Tool

MF33 Hot-dip Galvanizing Friction Bolts Underground Gold Mine Support Tool

Description: 

Friction bolts are a critical ground support solution used in mining to provide rapid stabilization of rock masses. They are designed for quick and efficient installation using standard drilling equipment, making them ideal for environments where immediate reinforcement is necessary to prevent rockfalls or collapses.

Specification:

Application:

Copper mines;
Gold mines;

Other metallic mines;

They are installed by extrusion, where the bolt is forced into the drill hole, creating axial and radial frictional forces that secure the rock strata. This mechanism produces massive supporting force, ensuring roadway and tunnel stability.

Feature:

Made fromhigh-yield, high-strength steelfor superior durability.
Features a high-quality welded ring that maintains strong adhesion even under stress.
Even if the bolt body fractures, the welding ring remains securely in place, preventing sudden failures.
Available in black (uncoated) or hot-dip galvanized versions for enhanced corrosion resistance in harsh mining environments

Advantage:

Can be installed quickly with standard equipment, reducing labor costs and downtime.
Engineered to withstand heavy loads and dynamic rock movement.
Hot-dip galvanized versions provide long-term protection in wet or acidic conditions.

Package:

Friction bolt package is bundle, plate by pallet.
