The authors develop standards and design of pre-emergency, emergency and post-emergency control of mine technological environment and electric machinery activity. The electric machinery operation parameters to be controlled are energy supply of explosion-proof electric machinery, cable integrity and improper access to the machinery; the control objects are switchers and starters within an extraction district. The technological environment parameters to be controlled are gas content, including CH 4 , CO, CO 2 and O 2 , variation in mine air pressure, light, sound, temperature, acceleration or dislocation of central control unit housing. The article presents engineering solutions on subsystems of data reading, processing and storage. CONCLUSIONS 1. The authors have developed the basic standards and characteristics of PECS meant to accomplish continuous integrated control over state of electric equipment and air in coal mines and prevent from the equipment operation infringement that, together with impermissible methane concentration, is the cause of explosions in mines.2. In cases of emergency, the systems run the objective documentary control and record of the mine area parameters in the accident and post-accident mode.3. The authors present engineering design of the data processing, storage and retrieval. 4. The designed and manufactured brassboards of the PECS subsystems have successively passed probation. Engineering design of the remote wireless data transmission, low-voltage network communication and program support of the data acquisition and transmission subsystem have been developed.
