PRESS RELEASE


 

BOGDANKA IS TESTING WIRELESS CONNECTIVITY IN THE MINE

 

LW Bogdanka, the technological leader of Polish hard coal mining sector and a member of the Enea group, has tested a wireless communication system underground. The implementation of this new system makes part of the Company’s strategy and is to be completed in the future. It is part of the “Smart Mine” programme. The implementation of wireless communication and transmission of data underground is meant to increase work productivity, limit time spent on standstill of the machines and increase the safety of employees.

In one of the extraction brigades, the employees have spent four weeks testing the functionality of the wireless connectivity system. The communication devices were given to the leader of the longwall, coal-cutting machine operators, section specialists, leaders of the upper and lower recesses, as well as crew of the wall scraper and belt conveyors.

 

“We are considering multiple options to improve work in Bogdanka, currently we are analysing the possibility of implementing underground wireless communication, which has not yet been used in any mine in Poland until now. Although we are aware of the need for improvement of some elements of the system at hand, the trials and tests have confirmed that the implementation of wireless communication and transmission of data also underground can significantly improve work - just like it once changed the way the mine functioned on the surface. Safety factor is also very important. We are extracting seams that demand even greater caution. Access to mobile communication can minimise risks in the everyday work of the miners”- said Artur Wasil, President of the Management Board in LW Bogdanka S.A.

Currently, employees working underground communicate at a distance using gestures and signs produced by light. A fixed line telephone network is also in use, however it does not enable a stable flow of communication - it is limited by the number of telephones and their location. The wireless connectivity system would enable an uninhibited ability to communicate for persons equipped with its devices and thus eliminate standstills, allow tasks to be coordinated and staff to be safely withdrawn from a particular area, for example from longwall crossings, when necessary. It means greater efficiency, time savings, and above all greater safety for underground works. 

The system that is being tested in Bogdanka is a solution meant for underground work in mines, including those at risk of methane and coal dust explosions. The system creators programmed electronics and created software which runs audio traffic in a distributed network.

The connectivity takes place in two directions, like in a mobile network. The system consists of personal communicators (radiotelephones placed on a mining helmet in the form of headphones), repeaters (transmitters distributed in excavations, retransmitting radio signals thus creating a wireless backbone network), M1 base (central quarters of communication management in the network) as well as media converters (active elements in a fiber-optic network; optional repeaters can be connected by a fiber-optic network via media converters). A noise reduction system ensures good sound quality.

Additionally, the system is equipped with a special application which enables communication with miners and rescuers, as well as observation of their direction of movement and location in the excavation.

Lubelski Węgiel Bogdanka S.A. is the only mine in the Lublin Coal Basin which extracts hard coal. The Company conducts mining operations within the mining area of Puchaczów V which covers 73 km2. It possesses three excavating fields: in Bogdanka, in Nadrybie, and in Stefanów. In autumn 2017, the Company obtained from the Minister of the Environment a mining licence for extraction of hard coal from the Ostrów deposit in the Ludwin Mining Area.
