Purpose. To identify indicators of massif zonal structuring around underground working using numerical modeling techniques.
Methods. Research into massif zonal structuring was performed using finite element method and thermodynamic method by which the size and number of zones formed around development workings and stopes have been simulated.
Findings. The ratio of zones’ vertical and horizontal semiaxes in the massif has been established and reliability of the obtained results was determined. The prospects of new modeling techniques for the study of massif zonal structuring parameters around underground workings have been identified.
Originality. The opportunities for wide application of numerical simulation methods to study the phenomenon of zonal encapsulation by the massif of underground workings have been revealed.
Practical implications. The sizes and shapes of zones in the massif around workings were determined and requirements were formulated stating that synergetic research methods should allow to more accurately determine the number, size and shape of zones, as well as fading sinusoidal stress and massif strain domains.
