Safety-Certified Underground Conveyor for Coal Mining Operations
Overview
When underground production depends on reliability, our Long-Distance Underground Belt Conveyor with Explosion-Proof Drive Station delivers. Designed for deep mines and confined tunnels, it provides a continuous, clean, and explosion-safe material transport solution that ensures your operations never stop.
Core Advantages
1. Built for Harsh Environments
Made from reinforced frames and anti-abrasive rubber belts, this conveyor resists corrosion, dust, and mechanical wear — ensuring stable operation in wet and high-dust zones.
2. Safety at Every Level
Explosion-proof motors, emergency stop systems, belt alignment detectors, and temperature monitoring sensors protect your workers and keep operations compliant with mining safety regulations.
3. Engineered for Efficiency
The system minimizes transfer stations, reduces power loss, and improves the efficiency of long-distance transport — all while lowering maintenance and operating costs.
4. Flexible Installation
Whether your mine has horizontal galleries or steep inclines, the modular structure supports multi-angle, multi-directional routing, adapting easily to complex underground layouts.

Technical specification
| Parameter Name | Unit | Example of parameter values | Remark |
| Delivery capacity | t/h | 300 - 2000 | The cost of belt conveyors varies depending on their application and model. For instance, when used in coal mining faces for transportation, the cost may be lower, while when used in main transportation roadways, it may be higher. |
| Conveyor belt speed | m/s | 1.2 - 3.5 | The speed selection takes into account factors such as material characteristics and conveying capacity requirements. |
| Conveyor belt width | mm | 650/800/1000/1200 | Different bandwidths adapt to different conveying volumes and roadway conditions |
| Conveyor belt length | m | 50 - 5000 | It is determined by the actual transportation distance of the underground roadway |
| Conveyor belt length | kW | 11 - 500 | The power size depends on the conveying capacity, length, slope and other working conditions |
| Maximum lift (tilt) Angle |
| 0 - 20 | It is related to the properties of the material, such as the fluidity and friction of the material. |
| Conveyor belt type |
| It is related to the properties of the material, such as the fluidity and friction of the material. | Layered fabric cores are suitable for medium and short distances and medium to small transportation volumes. Steel wire rope cores are suitable for long-distance, high-volume and high-tension applications |
| Roller diameter | mm | 89-159 | The diameter of the idler roller affects the support effect and service life of the belt. Large-diameter idler rollers are generally used for large transportation volumes. |
| Idler spacing | m | 1-1.5 (Load-bearing idler rollers)
2-3 (Return Rollers) | The diameter of the rollers affects the support effect and service life of the belt. Larger rollers are generally used when the transport volume is high.
Roller diameter |
| Type of tensioning device |
| Weight tensioning/screw tensioning/hydraulic tensioning | The heavy hammer tensioning can automatically maintain the tension. The screw tensioning is simple, but the tension adjustment range is limited. The hydraulic tensioning can automatically adjust, and the tension is stable. |
| Level of protection |
| IP54 - IP65 | It is used to indicate the dust-proof and water-proof capabilities of motors and electrical equipment. Generally, a higher protection level is required in underground environments. |
| Hazardous rating |
| Exd I/Exd II | It is used in underground environments with flammable and explosive gases, such as gas, to ensure the safe operation of equipment. |
