Abstract. In this study, the use of the concordance coefficient according to Kendall's formula for expert assessment of the geophysical state of mining massif is thoroughly examined. There are various methods for expert assessments, one of which is the ranking method. In this method, experts are asked to rank quantities or factors in order of their influence, assigning ranks from most influential to least influential on a scale from 1 to n (the number of ranked factors). One drawback of this formula is the inability to consider the level of competence when conducting expert assessments. The proposed new approach involves taking into account the level of competence of experts providing recommendations regarding the influence of various factors on the geophysical state of the mining massif. Through scientific research, an analytical dependence (formula) for the concordance coefficient has been determined for the first time, considering the level of competence of experts in the field. A specific example of calculating the concordance coefficient is provided, demonstrating the significant impact of the experts' qualifications on the calculations of the concordance coefficient. The obtained data emphasize the importance of the experts' qualifications for the accuracy of concordance coefficient calculations. Such an approach allows for consideration not only of mathematical aspects but also of expert knowledge to ensure more informed decisions. The discussed analytical dependence enables comprehensive assessments by incorporating expert recommendations. The presented conclusions shed light on the practical aspect of utilizing the results for evaluating the geophysical state of mining massif. The research underscores that accounting for the qualifications of experts is a crucial element in assessing the geophysical state. The acquired data can be employed to support effective decision-making in the field of mineral extraction. Considering the level of expertise of experts enhances the reliability of information obtained during the assessment of the geophysical state. The research findings can be practically applied for a comprehensive evaluation of the geophysical state of a massif of mining rocks. In summary, the use of the concordance coefficient according to Kendall's formula, taking into account the qualifications of experts, contributes to a more accurate determination of the geophysical geophysical state of a massif of mining rocks.
Keywords: geophysical condition, expert assessment, concordance coefficient, Kendall's formula.
