Purpose of mine vent network (MVN) operation is maintenance of permanent state of mine atmosphere by its composition, temperature and humidity for providing normal vital activity of people during their working under ground. The MVN failure means complete or partial non-fulfillment of this function resulting in content of toxic and explosive gases and dust exceeding the maximum permitted values. Formation of dangerous and extraordinary situations in the vent system is the result of manifestation of a certain aggregate of factors of aerological risks. In this article, the main types of emergencies, which arise up in the mine as a result of or lead to the MVN failure, are described, and cause-effect relations between undesirable events resulting in an extraordinary situation, basic factors of aerological risk and ways of their minimization are analyzed. It is shown that for quantitative estimation of aerological risk of emergencies in winning areas, it is necessary to apply rationing coefficients (ranks), which characterize its share in creation of the most unfavorable situation. The method of expert evaluation is the most suitable for the risk estimation. It is recommended to process the information given by experts by the method of analysis of hierarchies. Mathematical body of the risk calculation assumes processing of ranks of emergency factor meaningfulness by taking into account their weight and contribution to the root event – the extraordinary situation. The factor weights are put in the tree of cause-effect relations and are calculated from extreme branches (primary causes) to the root of tree with taking into account interrelations between the factors. It is concluded that the major task for improving safety of the mining works is to reveal all factors of aerological risk, their interrelation and interaction and to develop methods for risk minimization with the use of modern methods of simulation - from mathematical method to expert evaluation. Thereby, the major task of the labour protection control systems in dangerous production object – to ensure an «acceptable risk» in all units of the coal production - will be solved.
