Description	The technique of pressure balancing to combat/control underground coal mine fires is universally accepted. The technique is used in many coal mines in India and results are encouraging. However, presently adopted manual pressure balancing technique is a tedious process and sometimes call for expert attention over a long period. To overcome these difficulties a microprocessor based automatic pressure neutralization device eliminating the need for continuous human attention is proposed. The detailed functions of the proposed device, control logic, and its flow chart are highlighted. The theory of pressure balancing technique and limitations of the manual system of pressure balancing technique are also dealt with. The salient features of the device and its placement in the mine are illustrated with suitable schematic diagram. Advantages of the system and necessary precautions to be taken while fabricating the same are also outlined. The program logic of the proposed device is illustrated in the form of a flow chart.
