MODELING THE STABILITY OF MINING EXCAVATIONS

https://doi.org/10.48498/minmag.2025.238.2.007

The study focuses on modeling the stress-strain state of mine workings with anchor support under various seam dip angles and excavation shapes. The conditions of seam K10 at the «Abayskaya» mine of Qarmet’s mining division are considered. Numerical simulations were conducted using the ANSYS software package. The research examines the influence of excavation geometry and coal seam dip angle on stress distribution within the rock mass. The objective is to optimize support parameters to ensure the stability and safety of mine workings. The results highlight the importance of accounting for geological factors and excavation geometry in the design of supports under complex mining and geological conditions.
