Rock Pillar Fracture-Induced Vibration Characteristics and Rock Burst Mechanism in Steeply Inclined Extra-Thick Coal Seam Group Mining

Clarifying the dynamic mechanism of rock pillar fracture and its rock burst-inducing mechanism is fundamental for the prevention and control of rock burst disasters in steeply inclined extra-thick coal seam groups. In this study, field monitoring, theoretical analysis, and numeri...
