Tactics of mine ventilation failure restoration toward safe atmosphere control

Authors: Ushakov V. K.

Safe atmosphere control in mines is aimed at improvement of reliability and operating efficiency (ROE) of mine ventilation systems (MVS). The early tactics of ROE improvement is recovery of an MVS. In the framework of development of a tactics to select a rational failure restoration method, some rules were formulated and classified into two groups: (1) tactical rules for random failure restoration and (2) tactical rules for degradation failure restoration. The first group rules administer selection of repair procedures for MVS components broken by the moment of failure (repair of broken ventilation structures, removal of rockfalls in tunnels, actuation of broken-down main fans), with simultaneous detection of imperfect repair of broken elements. The degradation failure restoration rules govern selection of measures on erection of new ventilation structures, widening of underground excavation or installation of new support systems, or boosting of main ventilation fans. In compliance with the regulatory documents, the rule of selecting branches–drip legs of MVS segments is chosen as a tactical measure. In order to reduce the number of the required measures, the rules based on heuristical principle of minimizing the cross-effect of the farthest branches are applied. The formulated tactical rules and the related matrices of the influence branches make it possible to identify both the sites and the priority of tactical measures to be implemented. The increase in the recoverability of MVS results in the enhanced safety of mining operations by the criterion of airing, and in the mine personnel comfort.

Keywords: mine personnel safety and comfort, mine ventilation system, reliability and efficiency, principle of rational tactics of serviceability recovery, selection of tactical measures, tactical rules, matrices of influence branches.
