Use the numerical modelling analysis approach to compare the actual mining face (315m) with the designed mining face (200m). The results show that the large-size mining face has a larger peak abutment pressure and a larger stress concentration factor than the general-size mining face. Mining intensifies roadway stress, causing greater displacement of its roof, floor, and walls. To tackle the intensified pressure from the expanded mining face, we developed a hydraulic fracturing pressure management plan. This plan was crafted through meticulous theoretical studies and computational models, and it has since undergone rigorous field testing.
