The task of developing a multifunctional safety system in coal mines (MFSS) as a means of improving industrial and mine safety has been addressed by developers, operators and supervisory authorities alike. One of the directions in solving this task is to improve the normative base, among which the "Safety Rules in Coal Mines" Code of Federal Regulations (FNiP) takes its special place. A significant part of the MFSS is the systems that provide communication, warning and positioning of people in mines. The design and development of these systems are consistent with the level of requirements contained in the "Safety Rules in Coal Mines". This paper presents a compliance assessment of different system designs, i.e. continuous positioning systems within the whole extent of mine workings and the zone-based systems with accuracy within a part of mine workings. The paper argues that it is advisable to introduce a requirement regarding the accuracy of people positioning in order to increase the reliability of data obtained in both types of systems that are best suited to ensure the rescue for people caught in an accident. The research also shows that in order to develop a technology to monitor the composition of the mine air, it may be useful to introduce requirements for equal use of gas analyzers built into the head lamp with the conventional portable gas analyzers, which would allow for a successful implementation of scanning gas control.
