Bearing Plates for Rock Bolt Ground Support Systems
Discover how our premium bearing plates provide maximum load distribution and secure your ground support systems in complex geological conditions.
Rock bolt plates, also widely known as anchor plates or bearing plates, are critical accessories in modern rock bolt support systems. Their primary engineering function is to transfer bolt pre-tension and support force directly to the rock surface, ensuring high-integrity ground stability.
By providing a robust contact interface, these plates prevent local rock crushing and ensure the bolt works as a unified reinforcement element within the strata.

Download Technical SpecsCommon Ground Support Problems Caused by Wrong or Weak Bolt Plates
In mining roadways, tunnels and slope support projects, rock bolt plates must handle uneven rock surfaces, load distribution, weak ground, mesh protection and installation angle deviation. Choosing the wrong plate may reduce support stability.
Uneven Load Distribution
Point-loading occurs when force is concentrated on a small area, leading to plate deformation and bolt failure.
Uneven Rock Surface
Jagged rock faces prevent standard flat plates from making full contact, reducing effective support.
Weak Rock Crushing
Soft or fractured strata can crumble under high tension, causing the plate to "dig" into the wall.
Loose Rock & Mesh Failure
Small debris can fall through mesh if the plate doesn't provide adequate clamping force against the net.
High-Stress Deformation
Deep-level mining creates extreme squeeze. Rigid plates may snap or yield under massive tectonic pressure.
Cable / Pipe Hanging Needs
Standard plates lack the infrastructure to support necessary underground utilities like air/water lines.
Stop Compromising On Mine Safety
Don't let inadequate ground support become a liability. Consult our engineers for the exact plate for your rock density.

4 Critical factors to ensure ground support integrity and project ROI.
1. Assess Ground Conditions
Analyze rock mass rating (RMR) and seismic potential. Soft rock requires larger surface area plates to prevent punching, while hard rock focus is on tensile capacity.
2. Match Bolt Type & Load
Ensure the dome size and hole diameter match your specific anchor (Threaded bolts, split sets, or cable bolts) to maintain optimal load distribution.
3. Environmental Factors
High salinity or humidity requires specialized coatings. Choose between Black Steel, Epoxy, or HDG based on the project's expected life cycle and soil chemistry.
4. Installation Angles
Verify spherical seat clearances. Our premium domed plates accommodate angle deviations up to 18 degrees while maintaining full surface contact.
