Abstract. In the article, the authors discuss a risk oriented approach to monitoring and control of technical condition of the shaft hoisting complexes, which assumes the transition from the reactive principle of control to proactive, that is, from compensation for damage to the prevention of industrial injuries and accidents in mine shafts. Risk-forming factors at the stages of the life cycle (design, construction and operation) of the hoisting plant in vertical shafts and mines were determined. Technological, technical and evolutionary groups of risk factors, which are external or internal in relation to the shaft and its equipment, are considered. Anomalous changes in the properties of hoisting plant are revealed, which are formed as a result of its long-term operation. These include geometric, kinematic, physical-mechanical, dynamic, power and deforming anomalies. The main processes that lead to risk of failures of mechanical devices in shaft hoisting plant and emergency hazardous situations are considered. The of risk factors are classified by criteria of time, controllability and material damage values. A schematic diagram was built for relationships between the risk-forming factors and unfavorable events in a shaft hoisting system, which reflects the effect of risk factors on the probability of adverse events in the hoisting system, which allows to determine the risks of these events. It is shown that the main parameters that characterize the degree of emergency hazard of the "conveyance – shaft framework" systems are the strength margin of each load-carrying element of the shaft framework and margin for the engagement between the rigid guides of cage and guides of the shaft. Methods for calculating risk indicators during the operation of the "cage – shaft framework" systems in complex mining conditions were developed. The directions of the risk oriented approach to the control of shaft hoisting systems during mining operations are determined, the main of which are the real-time automated control of equipment parameters and identifying of risk for the key parameters by periodic or continuous monitoring with using specialized expert systems.
Keywords: shaft hoisting, shaft, shaft conveyance, shaft framework, risk forming factors.
