Flame Retardant Steel Wire Rope Core Conveyor Belt

The mandatory-compliance belt for underground main gate conveyors — combining steel cord tensile strength with certified flame retardancy and built-in anti-tear protection.

Underground Coal Mine Main Gate Conveyors

The core application. Mandatory FR certification and anti-tear protection make this the required belt type for main haulage routes in underground coal operations.

Underground Trunk & Panel Conveyors

Long face-to-surface haulage routes where belts run continuously under heavy load in enclosed, gas-present roadways.

Longwall Gate Road Installations

High-speed, high-tonnage gate belt conveyors where tramp metal risk from shearer operations makes anti-tear mesh essential.

Underground Tunneling Projects

Extended tunnel boring and civil excavation projects requiring certified flame retardant conveying equipment throughout the works duration.

Underground Main Haulage, Zero Compromise on Safety

The Flame Retardant Steel Wire Rope Core Conveyor Belt is the designated solution for underground conveyor systems where fire safety certification is not optional — it is a regulatory requirement. Manufactured in strict compliance with HG/T3646—1999, this belt takes the high-tensile, long-distance capability of a standard steel wire rope core and adds two critical safety upgrades specific to underground mining duty.

First, the cover compound is formulated to meet mandatory flame retardancy and anti-static standards, preventing fire propagation in enclosed underground environments. Second — and most distinctively — one or two layers of anti-tear mesh are embedded between the cover rubber and the core compound. This mesh layer, available in steel wire or woven fabric construction, physically blocks foreign objects from penetrating the belt body and propagating a longitudinal tear.

Why Anti-Tear Mesh Changes Everything Underground

  • Positioned between the top cover rubber and the core compound — precisely where penetrating objects make first contact with the belt structure
  • Available in steel wire mesh for maximum interception strength against hard metallic objects
  • Available in woven fabric mesh for applications where belt flexibility and weight are priorities
  • One or two mesh layers are configurable, depending on the severity of the foreign object risk in your specific loading conditions

Key Features

Anti-tear mesh, certified flame retardancy, and steel cord tensile strength — all in a single underground-rated belt.

Built-In Anti-Tear Mesh Layer

One or two layers of steel wire or woven fabric mesh embedded between cover and core — physically prevents foreign object penetration.

Certified Flame Retardant

HG/T3646—1999 compliant; mandatory requirement for underground main gate.

Anti-Static

 Continuous static dissipation to eliminate ignition risk in dust-laden and methane-present underground environments

Ultra-High Tensile Strength

Steel wire rope core supports ST630–ST5000 tensile grades for long-distance, high-load conveying routes

Long-Distance Capability

Engineered for main haulage systems spanning hundreds to several thousand meters in a single flight

Foreign Object Penetration Resistance

Anti-tear mesh intercepts tramp metal, rock fragments, and sharp material before they can split the belt longitudinally

High Splice Integrity

Open-structure rope core with full rubber infiltration ensures maximum vulcanized splice strength and longevity

Excellent Troughing

 Steel rope core forms a consistent trough profile that transitions smoothly to flat, reducing edge wear

Why Underground Operations Specify minsenmine

HG/T3646—1999 Certified Production

Every flame retardant steel wire rope core belt we manufacture is tested and documented to HG/T3646—1999. Compliance certificates and full quality records ship with every order — ready for mine safety inspection.

Anti-Tear Mesh Integrated in Manufacturing

The mesh layer is not a post-production addition. It is laid and vulcanized into the belt structure during the primary manufacturing process, ensuring consistent bond strength between mesh, cover, and core throughout the full belt length.

Configurable Protection Level

Single or double mesh layers, steel wire or woven fabric mesh type — specified to your loading conditions and foreign object risk profile. We work with your engineering team to determine the right configuration before production begins.

Factory Direct from Shandong

No intermediaries. Direct manufacturing lead times, competitive factory pricing, and a single point of contact from specification through delivery.

FAQ

In China, underground coal mine conveyor belts must comply with mandatory flame retardancy and anti-static standards under coal mine safety regulations. The Flame Retardant Steel Wire Rope Core belt (HG/T3646—1999) meets these requirements for underground main haulage applications.

Steel wire mesh provides higher interception strength against hard metallic foreign objects and is recommended for installations with significant tramp metal risk, such as near shearer or continuous miner operations. Woven fabric mesh offers good tear resistance with slightly less weight and better belt flexibility, suitable for applications where the primary risk is rock fragments or fibrous material.

Yes. Single-layer mesh is standard for most applications and provides substantial protection against penetration. Double-layer mesh is specified for particularly high-risk loading conditions or where the consequences of belt failure are severe enough to warrant the additional investment.

The mesh layers are accommodated in the splice step calculation. Vulcanized splicing is required and the step pattern must account for mesh layer positions to ensure full strength is achieved.

Tensile grade depends on conveyor length, belt width, load per meter, drive power, and installed take-up. Provide us your conveyor layout data and we will calculate the minimum required tensile grade and recommend a specification.

Yes. Every belt ships with the production test report, material certificates, and HG/T3646—1999 compliance documentation. These records are available for submission to mine safety inspection authorities.
