Abstract: An algorithm is proposed for controlling the ventilation system of an underground mining enterprise in which automatic ventilation doors (AVD) are located in the mine workings of main directions, and it is possible to switch the discharge fans of mine air-heating units (MAHUs) into a reverse mode (when air is directed to the surface from air-supplying trunks). In case of emergencies, the proposed algorithm allows to reduce the time for reversing the direction of air movement and to ensure safety in various situations associated with possible options for failure of the AVD.
Thanks to the use of pre-fabricated mine air stoppings of a new type, it is possible to isolate mining sites from the ingress of flue gases in advance in an automated mode, determining the places of their construction, including using the "Electronic plan for the elimination of accidents.
