Russia makes super-phones in mines

A team of scientists from the Far Eastern Federal University has built a unique wireless communications system for miners.

"This is an ambitious task, which is fivefold more than the signal power of the Russian Voice," said Vladimir Korochentsev, head of machine-building at the Far Eastern University. Existing equipment. "There are no wireless systems in the world that can provide communications at distances greater than 1,000 meters," he said. While the British system can provide communications at a distance of 150 meters, this Russian system can signal far from 1,500 to 2,500 meters depending on the mineral composition of the underground.

According to Russian scientists, in certain locations, radio waves can penetrate deep underground. It is essential to determine the permeability of the ore and to provide the appropriate frequency.

Following a recent major accident at the Raspadskaya mine, the Russian government has decided to increase safety in the coal industry, especially the wireless communications facilities for mines. At present, Russia has signed an agreement with China to provide wireless communications equipment to the country.

The wireless communications system developed by Vien Dong scientists was tested at the Vostok-2 mine in Primorie (Russia) and some mines in China. In the next phase, the team will study the production of emergency notification systems. Vladivostok (Russia) scientists are ready to provide this communication system for all mines in Russia and China within two years.

Physicists at Far Eastern University are interested in creating personal communications equipment - a must for all miners and people working in underground works.
