Underground Communication From Becker

The Beckercom leaky feeder allows miners in the mine to utilize underground communication using standard two-way radios. This greatly increases safety and productivity. The leaky feeder system allows for the monitoring and control of electrical equipment such as fans and pumps. The Intrinsically Safe (I.S.) Leaky Feeder, when used in conjunction with the Becker I.S. can provide 100% coverage to underground mines. 

System Operation 

This system allows seamless communication between two parties in underground tunnels and mines. This is possible by using leaky feeder antenna cables. Leaky feeder antenna cables transmit radio signals underground. These signals are typically located at the surface. It is possible to retransmit the signal on the surface, and it can travel several kilometers.

Leaky Feeder Cable 

The coaxial cable was created to preserve as much signal as possible while blocking external signals. Leaky Feeder cables can leak radio signals or radiate them out. They also allow signals from remote radio transceivers within 50-200m of the Leaky Feeder cable. Traditionally, boosters or line amplifiers are placed along the Leaky feeder cable runs. They are typically installed every 350m. They are used to maintain signal levels over long distances.

System Design

In consultation with customers, certified Becker communication engineers design leaky feeders and comply with all compliance requirements.

Extensions And Repairs

Leakage in Feeder cables is a constant problem as a mine grows. To minimize downtime and maintain reliable operations, it is crucial to quickly connect and repair any damaged Feeder cables. The Becker splice can meet these requirements. Line splices can be used to connect two sections together where signal amplification is not applicable or to repair damaged sections. Line terminations must be placed at the Leaky Feeder cable to properly terminate the system. 

TWO-WAY RADIO

The Becker UHF radio is intrinsically safe I.S. The portability of radios is a great way to have reliability and versatility in a compact and rugged package.
