Abstract: Enhancing the reliability and efficiency of mine ventilation systems is one of the most urgent and complex tasks in ensuring the safety of mining operations. During the first stage of improving the reliability and efficiency of mine ventilation systems the developed method of selecting a rational approach to restoring the system performance (the ‘tactical’ method) is used, which allows to increase the recoverability of the system without changing its baseline configuration. This results in improving of both the availability ratio of the mine ventilation systems due to a decrease in the average recovery time, and the longwall production rates because of decreasing downtime due to the ventilation factor. The 'tactical' method is used in the process of modeling the base case of mine ventilation systems to select measures that would ensure rational strategies to address current failures of the system, i.e. recurrent disturbances of the required air distribution modes. The algorithm of the 'tactical' method is based on the optimal control of air distribution with the help of dynamically selected tactical measures with due account for the duration of their implementation. The stage of improving the reliability and efficiency of mine ventilation systems by applying the 'tactical' method involves implementation of the approach to rationally select the locations and priorities of measures to address the failures based on segmentation of the mine ventilation systems and the use of tactical rules. The lists of proposed tactical measures are designed as influence matrices. Initially, the shortest of the proposed measures are selected and the air distribution is controlled using simulation of these measures. For those of the selected measures that were required for regulation, the costs of their implementation are calculated, and those that were not used are excluded from the list of the proposed measures. Execution of the 'tactical' method algorithm is completed either when the operation of the mine ventilation systems is restored, or when the list of suggested tactical measures, selected with the unchanged structure of the mine ventilation systems, is exhausted. Enhanced recoverability of the mine ventilation systems results in both increased safety of mining operations in terms of the ventilation factor and ensuring comfortable working conditions for the miners.
