In the article are considered practical aspects of the indoor positioning and emergency alert systems for personnel as a parts of multifunctional safety systems in coalmines. It is shown, that currently existing systems in the mines for this purpose, do not meet the requirements of the Safety Rules in coalmines, taking into account the changes introduced by order of Rostekhnadzor of October 31, 2016, No. 450. The main deviations from the current requirements inherent in such systems is determination of the location of workers in the mine to the accuracy of mine’s areas (with the requirement to provide a resolution of ±20 m), as well as, the lack of guarantees in emergency alerts delivery to the miners. It was formulated main directions for solving these problems by the complex application of cable and wireless communication channels, as long as continuous radio field covered the workings areas and individual mobile devices are in touch with the underground communication network. Described main parameters and properties of the multifunctional communication system, observation, alerting and searching for people caught by the accident, «SBGPS», produced by the research and production company «Granch».
