Abstract
To address the production succession challenges posed by single-wing mining, this study investigates the 5-1081 roadway of the Fenyuan Coal Mine as a representative example. Theoretical analysis and numerical simulation were combined to systematically examine the spatiotemporal relationship between the gob-side roadway and the overlying working face, with a focus on their influence on excavation strategies and surrounding rock deformation. The results indicate that, under a fixed coal pillar width, the adjacent mining and driving scheme significantly enhances surrounding rock stability and reduces succession constraints compared to other methods. Under this scheme, the roadway undergoes pronounced asymmetric deformation, with significant disturbances occurring especially before and after the intersection with the working face. Based on the deformation characteristics, a segmented support strategy was proposed, defining the key reinforcement zone as spanning from 40 m before to 60 m after the intersection. This study provides a theoretical basis and practical guidance for the safe and efficient construction of gob-side roadways under comparable geological and mining conditions.
