Research and application of grouting reinforcement technology for small coal pillar roadways along gob in extra-thick coal seams
Gob-side entry driving with small coal pillars in extra-thick seams improves resource recovery but is constrained by fractured, low-capacity surrounding rock and large asymmetric deformation. This study develops and validates a grouting-reinforcement technology that couples hollow high-pressure grou...
