Mine Safety and Efficiency

Mining Wireless Network Solutions for Underground and Open-Pit Mines | MAXON

As mining work areas deepen or move, wired infrastructure can be difficult to adapt. MAXON wireless access points and bridges provide network connections for underground tunnels, open-pit sites and mobile equipment. Mine operators and system integrators can use these components to plan communications for personnel, vehicles and fixed equipment.

Underground access points connect terminals in haulage tunnels and chambers, while wireless bridges can link equipment or separate locations at open-pit sites. Wireless links can also carry PLC and sensor data from pumps, fans and belt conveyors. In coal preparation and washing plants, wireless AP motherboards and intrinsically safe switches can provide connectivity for robotic equipment and terminals. Personnel positioning, dispatch and equipment monitoring use their respective terminals and systems; the wireless network carries communications to connected systems and the management center.

Wireless networking in underground mines

An underground mine wireless network can connect devices in working areas, haulage tunnels and chambers to a wider communications system. Industrial or explosion-proof wireless access points are network components used to provide wireless access. Personnel positioning and dispatch applications depend on compatible terminals and systems; the access point provides network connectivity.

For mine equipment monitoring, wireless links can carry PLC or environmental-sensor data from fixed equipment toward a central system. Pump and fan stations are examples of locations where wireless PLC connectivity may be useful when equipment moves or wired connections are impractical. Monitoring, analysis and maintenance decisions remain functions of the connected control or monitoring systems.

Wireless communications for open-pit mining

Open-pit mining sites may need communications between separated work areas, vehicles and operating locations. Industrial wireless bridges can carry telemetry, commands and video streams between network points. Point-to-point wireless bridge links connect two locations; point-to-multipoint links provide a way to connect multiple remote locations to a central point. The appropriate topology and equipment depend on the site network design.

Unmanned or remotely controlled heavy machinery, including dump trucks and excavators, can use wireless connectivity to carry data for their applications. The suitable equipment and link configuration depend on the site network design.

Wireless connectivity in coal preparation and washing plants

Robotic equipment in coal preparation and washing plants can use wireless clients and a MAXON wireless AP motherboard with intrinsic-safety certification for coal-mine applications. The owner confirms the board is intended for use across coal-mine scenarios. Contact MAXON for the certificate and product details. The board provides wireless connectivity; the robot’s operating functions remain with the robot and its control system.

FAQ

What is a mining wireless network used for?

It provides wireless network connections for mine personnel terminals, vehicles and fixed equipment, and can carry data between field locations and connected management systems. Positioning, dispatch and monitoring applications use their own compatible terminals and systems.

How do access points and wireless bridges differ in a mine?

Access points provide wireless access for nearby client devices. Wireless bridges connect separate network points, including through point-to-point or point-to-multipoint link arrangements.

Can a wireless link carry PLC data from pump or fan stations?

Wireless links can carry PLC and environmental-sensor data from equipment such as pumps and fans to a connected control or monitoring system. The PLC, sensors and system provide and use that data; the wireless network provides the communications path.

Can MAXON wireless equipment support robotic applications in coal preparation plants?

The intrinsically certified wireless AP motherboard can provide connectivity for robotic equipment across coal-mine scenarios. The robot and its control system provide the operating functions. Contact MAXON for the certificate and product details.

Does an explosion-proof product category establish suitability for every mine area?

No. Select the exact product model for the installation area and check its applicable protection markings and certification documents. The product category alone does not establish suitability.
