<p>Gob-side entry driving (GED) along the upper gob in an inclined coal seam (ICS) significantly differs from conventional GED because of the unique roof structure and rotational deformation pressure (RDP) from the cantilevered main roof block (block <i>B</i>). To address this challenge, a criterion for stability for a narrow coal pillar (NCP) was established on the basis of a cantilever beam structure (CBS) model, revealing that a 5-m NCP with a stability coefficient (<i>χ</i>) of 0.692 is insufficient to maintain stability. The effects of the length of block <i>B</i> and the integrity of the immediate roof on NCP stability were analyzed, which revealed that reducing the length of block <i>B</i> and decreasing the degree of damage (<i>D</i>) to the immediate roof can effectively increase stability. A calibrated UDEC model was developed to simulate the process of progressive failure of the GED, confirming the detrimental impact of the excessive length of block <i>B</i> on roadway stability. On the basis of these findings, a coupled control strategy was proposed that integrates hydraulic fracturing (HF) for roof cutting, an asymmetric anchor cable truss system, and grouting reinforcement of the coal pillar. Field application results demonstrated that the maximum roof-to-floor and rib-to-rib convergence were controlled at 330 mm and 379 mm, respectively, during excavation, significantly improving roadway stability. This study advances the understanding of GED stability in ICSs and provides innovative engineering solutions for large deformation control, thereby contributing to safer and more efficient mining operations.</p>
