Coal mines communication optical cable Application

1. Underground communication system

Voice communication:

used for real-time communication between miners and ground dispatch centers, supporting emergency command and daily communication.

Video surveillance:

transmitting high-definition video signals underground, monitoring the operation status of coal mining faces, transportation tunnels, equipment, etc., to enhance safety supervision capabilities.

Wireless communication base station interconnection:

provides backbone transmission channels for Wi Fi, 4G/5G mining base stations, and supports mobile terminal networking.

2. Safety monitoring system

Environmental parameter monitoring:

Real time transmission of sensor data such as gas concentration, temperature and humidity, carbon monoxide, and wind speed to the ground monitoring center.

Equipment status monitoring:

Collect the operating status and fault signals of underground equipment (such as fans, water pumps, belt conveyors) to achieve predictive maintenance.

Roof pressure monitoring:

transmitting roof displacement and pressure data through optical cables to warn of collapse risks.

3. Automation and intelligent control

Remote control of mining equipment

such as coal mining machines, tunneling machines, and hydraulic supports, relies on low latency and high reliability optical cable transmission commands for automated control.

Intelligent transportation system:

controls the operation of belt conveyors and unmanned mining cars to achieve automation of material transportation.

Power monitoring:

Integrated power communication network to monitor the current, voltage, and fault information of the underground power supply system.

4. Personnel and equipment positioning

UWB/RFID positioning system:

Connected to the positioning base station through optical cables, real-time tracking of miners and vehicle positions, combined with electronic fence technology to ensure safe area management.

Emergency broadcasting system:

Quickly broadcast evacuation instructions through fiber optic cable network in case of an accident.

5. Emergency rescue communication

Build a disaster resistant communication network to maintain smooth communication links in accidents such as gas explosions and water leaks, and support data transmission from devices such as life detectors and rescue robots.

6. Data Fusion and Intelligent Platform

Integrate production, safety, and management data to support applications such as digital twins and AI analysis, such as intelligent ventilation and disaster simulation warning.

Product Installation and maintenance

1. Regular inspection

Arrange dedicated personnel to regularly inspect optical cable lines, check for any damage, contamination, or construction issues, and promptly identify and repair them.

Regularly inspect key nodes such as splice boxes and distribution boxes of optical cable lines to ensure that the joints are in good condition, free from water immersion and debris accumulation.

2. Cleaning and maintenance

Regularly clean the optical cable, remove dust, dirt, etc. that may affect transmission, and keep the surface of the optical cable clean.

Fiber optic cleaner and wiping cloth can be used for cleaning. When wiping, pay attention to maintaining an appropriate angle with the fiber optic to avoid scratching it.

3. Fixed protection

Properly fix and protect the optical cable to avoid damage or breakage caused by external forces.

Check if the hanging point position of the optical cable is appropriate, ensure that the fittings and insulators at the hanging point are normal, and there are no discharge, damage, or other phenomena.

4. Waterproof and moisture-proof

Optical cables are prone to moisture in mining environments and require corresponding waterproof and moisture-proof measures, such as using sealing materials, waterproof sleeves, etc.

Regularly check if the fiber optic cable sheath is intact to prevent moisture from seeping into the interior of the cable.

5. Temperature control

The temperature fluctuation in the mining environment is large, and measures need to be taken to maintain a stable working temperature to avoid the impact of high or low temperature on the optical cable.

6. Maintain records

Establish maintenance records for optical cables, including inspection dates, maintenance content, maintenance personnel, and other information, to facilitate later tracking and management.
