Field and Numerical Investigation on the Coal Pillar Instability of Gob-Side Entry in Gently Inclined Coal Seam

In order to study the coal pillar stability of gob-side entry in gently inclined seam, a comprehensive method including theoretical analysis, numerical modeling, and field monitoring was applied its fracturing instability mechanism. The results show that uneven horizontal stress internal cause asymmetric deformation failure seam. rotation movement main roof distribution were closely related inclination Based on characteristics mechanisms entry, collaborative control technology cutting for pressure relief support strengthening has been put forward. research have practical significance revealing mechanism damage seam mining proposing engineering measures prevent disaster occurrence.
