The role of a mining machine operator gradually reduces to monitoring and managing a technological facility in difficult situations as mining automation increases. The increasing complexity of mining technology leads to the fact that the driver’s qualification must be very high in accordance with the requirements of modern mining processes. The main characteristics of the work of the career excavator driver in the «man-machine-environment» system are faultlessness, speed, accuracy, reliability. The effectiveness of the entire system depends on how the human operator’s participation will be organized in the process of managing the facility.

The article substantiates the necessity of setting the coefficient of determination for each of the sub-clauses when creating a rule base that takes into account the degree of influence of ergonomic properties in the study on the integrated assessment of the mine excavators’ ergonomics. A generally accepted scheme of ergonomic properties of mine excavators is performed, the weight coefficients of each of the properties are determined using the paired-comparison method. A fuzzy model has been implemented that allows determining the resulting level of ergonomics of the mine excavator cabs due to more precise adjustment of the input variables of the model.
