High - Tensile Steel Friction Bolts Rock Stabilization Tool

Description Of High - Tensile Steel Friction Bolts:

The friction bolt is constructed from high-tensile steel, precision-formed into a distinctive "C" cross-section (a design also referred to as a friction stabilizer or split-set).

The fundamental operating principle relies on a controlled interference fit. The bolt is forcefully driven into a drill hole with a diameter slightly smaller than its own. This action elastically compresses the steel tube, generating substantial radial pressure and friction against the surrounding rock walls.

This compression facilitates immediate and effective load transfer from the destabilized rock mass to the bolt and onto more stable ground strata. Crucially, this system delivers instantaneous reinforcement directly upon installation, eliminating any requirement for grouting, chemical resins, or other bonding agents, which significantly accelerates the support process.

Specification Of High - Tensile Steel Friction Bolts:

Application Of High - Tensile Steel Friction Bolts:

Friction bolts serve as a primary support mechanism in a wide range of underground mining operations, including copper mines, gold mines, and other metallic ore mines. They represent a cost-efficient, dependable, and straightforward-to-install ground support solution. These attributes establish them as the preferred option for mining projects that demand rapid and effective rock consolidation. Their extensive and validated track record in hard rock environments guarantees enhanced safety and ensures the structural soundness of tunnels, shafts, and other subterranean excavations.

Feature Of High - Tensile Steel Friction Bolts:

Fabricated from high-yield, high-strength steel for exceptional structural integrity and service life.

Incorporates a premium, robustly welded ring that ensures powerful adhesion to the rock surface, even when subjected to intense stress and shifting ground conditions.

Engineered for fail-safe performance: in the rare event of a bolt body fracture, the welded ring remains firmly anchored, preventing sudden and catastrophic support collapse.

Offered in either a standard black (uncoated) finish or a hot-dip galvanized coating to provide superior defense against corrosion in challenging and humid mining conditions.

Advantage Of High - Tensile Steel Friction Bolts:

Straightforward and Rapid Installation: Requires only standard drilling equipment, drastically reducing installation time and labor costs.

Exceptional Mechanical Properties: High yield and ultimate breaking strength to withstand heavy loads and dynamic rock movement.

Customizable Corrosion Protection: Galvanized versions are available for long-term reliability in wet or acidic environments.

Superior Anchorage Security: The welded ring design offers outstanding pull-out resistance, maintaining hold integrity under demanding conditions.

Package Of High - Tensile Steel Friction Bolts:

For secure and efficient handling, friction bolts are bundled together and systematically stacked on wooden pallets for shipment and storage.
