Abstract.

Main processes that lead to malfunctions in mechanical equipment of the mine hoisting systems, which can lead to emergency situations with heavy logistical and human consequences, are considered in the article. It is shown that state of operational safety of the mineshaft equipment depends on a set of four different factors: curvature of conductors due to mining and geological reasons; water inflows into the shaft; corrosion and mechanical wear of metal structures; and dynamic strength of metal structures under the influence of operational loads. The emergency-dangerous regimes of the mine hoisting plant operation are considered. It is shown that these regimes can be divided into two types by criterion of the situation evolution duration: emergency modes, which are monitored in real time by automatic devices of the plants, and hidden modes, which are associated with gradual development of micro-failures (micro-destruction, micro-wear, micro-tuning) accumulated in the equipment nodes. The risk-forming regimes are classified by criterion of controllability and severity of consequences. The corresponding classification schemes were developed. Parameters are determined, the control of which ensures completeness and reliability of information on the current state of the links of hoisting systems, which have the greatest effect on the safety of the hoisting complex.

Keywords: mine hoisting plant, shaft reinforcement, vessel-reinforcement, emergency situations at mine hoisting, risk factors of mine hoisting.
