1. Product Overview
The Resin Anchor Bolt is a high-performance rock bolting solution designed to stabilize roof strata in underground coal mining operations. It combines steel reinforcement with resin encapsulation technology, providing immediate load-bearing capacity and long-term durability. Ideal for longwall and shortwall mining, it ensures worker safety by preventing roof falls in low-to-medium thickness coal seams with gentle inclines (＜25°).

2. Core Features & Advantages
- Rapid Installation: Pre-packaged resin capsules enable quick curing (3–5 minutes), reducing downtime.
- High Load Capacity: Tensile strength up to 150 kN, withstanding dynamic loads from roof movement.
- Corrosion Resistance: Hot-dip galvanized steel rod and anti-corrosion coatings for harsh environments.
- Versatile Design: Compatible with W steel straps and metal mesh for composite roof support systems.
- Safety-Centric: Includes anti-detachment clips and torque-controlled tightening for secure anchoring.

4. Working Principle & Installation
- Drilling: Use a rotary drill to create a hole slightly larger than the bolt diameter.
- Insertion: Place the resin capsule into the hole, followed by the steel rod.
- Curing: Rotate the rod to mix resin components, forming a hardened bond with the rock.
- Tightening: Secure the anchor plate with a torque wrench to apply pre-tensioning force.

6. Maintenance & Safety Guidelines
- Inspection: Check resin capsules for moisture damage before use.
- Storage: Keep in dry conditions (＜60% humidity) to prevent premature curing.
- Installation Training: Provide operators with hands-on practice for proper torque application.
- Failure Prevention: Avoid over-tightening; use calibrated wrenches to prevent rod fracture.
