COMPUTER MODELING OF THE STRESS-STRAIN STATE OF THE NEAR-CONTOUR ROCK MASS

https://doi.org/10.48498/minmag.2025.241.5.006

The article examines the modeling of the stress-strain state (SSS) of the near-contour rock mass during the preparation and operation of mine workings. The relevance of the topic is associated with the need to improve the safety and effi ciency of mining operations at Qarmet JSC enterprises. Calculations of the SSS of the rock mass were performed using metal-arch and anchor supports. The infl uence of anchor length and diameter on stress distribution was established: longitudinal stresses increase with their growth, while shear stresses change insignifi cantly. Patterns of stress growth depending on the thickness of roof rocks were identifi ed. The research results, validated by industrial testing, demonstrate opportunities to enhance the stability of workings and develop adaptive support technologies for various mining and geological conditions.
