The diversity and commonness of the sensors used for monitoring industrial processes and the widespread use of the digital data processing methods for the measurements are crucial issues related to the communication and data collection. The popular technical solutions for fast and reliable transmission of large packets of information cannot be directly applied in an environment where the risk of explosion appears. The paper shows the physical layer limitations for the transmission links with the potential danger of explosion of methane and coal dust that are characteristic for coal mines. Areas of mine-specific applications for data transmission were summarized and an example of safety parameters calculation for the RS485 communication standard was presented.
