Underground mining environments require conveyor belts that can withstand heavy impact, moisture, fire risks and continuous operation. YUFENG Solid Woven Conveyor Belt is specially developed for underground coal mine transportation, using an integral woven textile carcass combined with PVC or PVG impregnation technology to create a strong rubber-textile composite structure.
Unlike traditional multi-ply fabric conveyor belts that may experience layer separation under repeated impact and harsh underground conditions, the solid woven structure integrates warp and weft yarns into one reinforced belt core. This design improves resistance against delamination, tearing and mechanical damage during heavy-duty conveying.
YUFENG independently manufactures complete series of solid woven belts with high-strength integral woven fabric cores. Designed for underground coal transportation, these belts provide reliable flame-retardant, anti-static, impact-resistant and tear-resistant performance for demanding mining applications.
With advanced production technology and strict quality control, YUFENG provides mining conveyor solutions covering general underground coal transportation, heavy-duty haulage systems and special working conditions requiring heat resistance, oil resistance or low-temperature performance.
YUFENG products comply with international quality requirements and can provide CE, MSHA, TUV, CEMA standard compliance support, SGS inspection reports and ISO9001:2015 quality management certification for global mining customers.
The performance of underground conveyor belts depends largely on carcass structure and material selection. YUFENG Solid Woven Conveyor Belt adopts a one-piece integral woven fabric core, where warp and weft yarns are woven into a compact reinforced structure before being fully impregnated with PVC or PVG compound.
The solid woven carcass eliminates traditional multi-layer bonding interfaces. This structure prevents separation between plies when the belt experiences repeated bending, heavy impact and sudden loading conditions.
The high-tenacity polyester and nylon mixed yarn system provides excellent tensile strength while maintaining flexibility around conveyor pulleys. This allows the belt to operate reliably in complex underground roadway layouts.
Different mining environments require different cover materials. YUFENG provides both PVC and PVG solid woven belt solutions according to material impact level, abrasion conditions and conveying requirements.
| Belt Type | Structural Feature | Suitable Application |
|---|---|---|
| PVC Solid Woven Conveyor Belt | The fabric core is fully impregnated with PVC compound, with PVC coating on both surfaces. It provides flame-retardant, anti-static performance with economical operation cost. | Suitable for general underground coal transportation, medium-light load conveying and conventional mining roadways. |
| PVG Solid Woven Conveyor Belt | The belt core is PVC impregnated and combined with an additional NBR/NR blended rubber working cover. It provides higher abrasion resistance, impact resistance and tear strength. | Suitable for heavy-duty underground mining, large lump coal transportation and high-drop feeding points. |
The main difference between PVC and PVG types lies in the working surface protection and impact-bearing capability. PVC models are commonly selected for standard underground transportation, while PVG models are preferred for high-impact main haulage systems where longer service life is required.
Mining projects require different belt strength levels according to conveying distance, material weight and loading conditions. YUFENG supplies a complete range of solid woven belt specifications with widths from 400mm to 2200mm and breaking strength grades from 680N/mm to 3150N/mm.
The belts can be matched with special solid woven belt idlers and standard trough idler systems, providing reliable integration with underground conveyor equipment.
Standard flame-retardant and anti-static PVC solid woven belts are designed for general coal transportation applications. They provide stable performance under underground safety requirements and are suitable for normal temperature conditions from -20℃ to +60℃.
Heavy-duty PVG solid woven belts are developed for environments involving large lump materials and frequent impact loading. The additional rubber working cover improves resistance against gouging, penetration and surface abrasion.
YUFENG also provides customized solid woven belt solutions for special conditions including high temperature, oil exposure and extremely cold environments.
Modified compounds can be selected for applications requiring temperature resistance up to 120℃, oil resistance against mineral oil and grease, or flexibility under low-temperature conditions down to -40℃.
Underground mining conditions vary significantly depending on coal size, conveying distance, feeding method and environmental factors. YUFENG provides customized solid woven belt solutions based on actual operating requirements instead of offering only standard specifications.
YUFENG supports customization of carcass strength grade, belt width, PVC or PVG structure, rubber cover thickness and special functional compounds. The available strength range covers 680N/mm to 3150N/mm to meet different underground transportation requirements.
For PVG models, customers can select customized rubber working cover thickness from 1.5mm to 6mm according to abrasion and impact requirements. Additional reinforcement layers can also be integrated for severe lump material feeding conditions.
According to different mining environments, YUFENG can provide functional modifications including flame-retardant and anti-static performance, oil resistance, high-temperature resistance, low-temperature flexibility and enhanced impact resistance.
These customized solutions help mining operators select the most suitable belt structure according to material characteristics, temperature range and underground working conditions.
Correct installation and proper maintenance directly influence conveyor belt service life. YUFENG provides technical guidance for belt cutting, splicing and conveyor system adjustment to ensure stable operation after installation.
Mechanical fastener splicing is commonly used for underground conveyor maintenance because it allows faster installation and repair. During installation, the belt ends should be cut evenly, keeping the woven carcass structure intact without damaging internal fibers.
High-strength mining belt fasteners should be installed with uniform pressure to avoid uneven stress concentration. After joint completion, tension testing should be conducted before normal operation.
For main haulage conveyors requiring permanent high-strength connections, hot vulcanization splicing provides a stronger and smoother joint solution.
During vulcanization, the surface coating is removed carefully while protecting the solid woven core. The two belt ends are accurately aligned and bonded with dedicated vulcanization materials under controlled temperature and pressure conditions.
A properly completed vulcanized joint can achieve joint strength close to the original belt performance, making it suitable for key underground transportation systems.
To maximize service life, YUFENG recommends matching solid woven belts with suitable conveyor components, including impact idlers, trough rollers and deviation correction devices.
For heavy lump material applications, buffer impact rollers should be installed at feeding points to reduce direct impact on the belt surface. Long-distance underground conveying systems should also include proper tracking devices to prevent edge damage caused by belt deviation.
YUFENG provides one-stop underground conveying solutions by supplying not only conveyor belts but also related accessories and supporting components for complete mining conveyor systems.
In addition to solid woven belts, YUFENG supplies sidewall conveyor belts, fabric conveyor belts, steel cord conveyor belts and patterned conveyor belts for different bulk material handling applications.
Supporting products include impact idlers, trough carrying idlers, return idlers, self-aligning rollers, pulley assemblies, conveyor skirting rubber, wear-resistant rubber sheets, belt repair kits and mining belt fasteners.
For international mining projects, YUFENG can arrange mixed-container shipments combining belts, idlers and related accessories. This helps customers simplify supplier coordination and reduce logistics costs.
Reliable performance starts with stable raw materials. YUFENG only uses qualified new materials and strictly controls material inspection before production.
The solid woven carcass uses high-tenacity industrial polyester and nylon mixed warp-weft yarns. The integral weaving structure creates a strong single-layer belt core with improved resistance against impact and tearing.
PVC type belts use virgin PVC resin combined with flame-retardant agents, anti-static additives and anti-aging modifiers. PVG belts add high-quality NR/NBR blended rubber covers to improve abrasion and impact resistance.
Each batch of fabric core, resin materials and functional additives undergoes laboratory testing before entering production. Tests include tensile performance, flame-retardant properties and surface anti-static resistance.
