Asymmetric Stress Evolution and Zoned Control of Gob-Side Entry Driving in Close-Distance Coal Seams Under the Influence of an Obliquely Intersecting Overlying Goaf Boundary
Gob-side entry driving (GSED) in close-distance coal seams (CDCSs) is subjected to complex loading paths when influenced by an obliquely intersecting overlying goaf boundary (OGB), making it difficult to determine an appropriate narrow coal-pillar width and limiting the adaptability of uniform support schemes. Taking t...
