DATA TRANSMISSION CHANNEL OPTIMIZATION IN MULTIFUNCTION SAFETY SYSTEMS OF COAL MINES

Multifunction safety systems (MSS) of coal mines are intended to prevent emergency situations due to various geodynamic, aerological and other industrial risks using methods and means of emergency protection and on-line control of consistency between process parameters and settings. Engineering or modernization of systems for monitoring, control and security involves modern equipment of long-range communication and programming support, which inevitably intensifies traffic in data channels of a mine. Data transmission channels must ensure high-rate and reliable passage of large bulk of process and emergency information. Therefore coal mines with explosive atmosphere, multi-branch system of roadways and complex geological conditions impose specifically severe requirements on communication channels as they should maintain the desired reliability of the whole multifunction information system. The multifunction mine safety system requirements are set by the state standard (GOST R 55154-2012). In mines categorized as gas-hazardous, communication channels receive signals from numerous varied subsystems of monitoring and control. In this case, it is necessary to ensure ranking and high rate of transmission of emergency signals. The article analyzes features of prompt transmission of emergency information in communication channels of a mine information system using multiplex lines, considering their capacity.
