Abstract: Safety is an important factor in the mining industry. Through-The-Earth technology can provide communication both in everyday usage and in a case of emergency. Developing the TTE communication systems raises a lot of questions about main system specifications such as a transmitting frequency, current and antenna geometry. This talk is about TTE system experiment in the Republic of Kazakhstan (“Irtishskaya mine”), researches in finding appropriate system specifications and antenna geometry, and finally the implementation of designed system in October 2017. Also we will speak about some propagation difficulties in the real mine and some engineering difficulties connected with mine electromagnetic environment.
In this talk we will represent experimental and numerical modeling results. We compare widely used loop antenna and grounded dipole antenna. One of the most interesting novel results is the influence of the antenna grounding depth to the signal level in the mine.
Biography: Ekaterina Korolkova is a senior teacher in the Siberian Federal University in the Department of Radio electronics teaching “Power supply of electrical systems”, “Networks and radio systems and information protection” and “Computer networks and Internet technologies”. Also she is a lead engineer in Research and Manufacturing Company “Iridium” which is designing radio electronics and doing research works in the field of seismic prospecting and seismic communications. She graduated from Irkutsk state university of railways in 2011 and for 5 years has been working in JSC “Russian Railways” projecting different telecommunication systems for the railways. In 2011-2015 completed Postgraduate studies in the field of system analysis, management and information processing. In 2013 had a title of “Engineer of a year 2013” nomination in “Youth engineering”. Now she is working on the designing the TTE mine communication system which in October 2017 was successfully implemented in the Republic of Kazakhstan in the mine “Irtishskiy”. Ekaterina’s research interests are in areas of mine and cell communication systems, radio electronics, signal propagation and through-the-earth communication systems.
