Assessment of the reliability of the human factor

Despite the general trend of injury reduction, the risk of injury to workers in the coal industry, especially in underground coal mining, is one of the highest both in Russia and abroad. Numerous studies have determined that the human factor is the cause of 70—90% of incidents, accidents and casualties. That is why any modern production facility requires a reliable forecast of injuries caused by incompetent actions of employees in order to plan managerial decisions aimed at reducing the number of accidents. Using a new model of the human factor, where the human factor is defined as a difference in time and space between the actual level of the complex of a person’s abilities and the required level of the complex of abilities, the methods of evaluation of the reliability of the human factor have been developed, making it possible to forecast the number of accidents. To make the forecast the results of determining the levels of employees’ competence obtained during the operation of the “Video information system of continuous development and control of employees’ competence in the sphere of occupational safety and health” at JSC SUEK-Kuzbass and data on the occupational traumatism were used. Results of calculations of reliability of the human factor and risks of traumatism for various groups of competence: competent, low-competent and incompetent are given. It is shown that continuous express training sharply reduces the probability of injury in low-competent and incompetent workers.
