Mechanisms and influential factors of rock bursts in tunneling roadways of extra-thick coal seams

Meitian dizhi yu kantan
ObjectiveRock bursts occur frequently in tunneling roadways of extra-thick coal seams, significantly constraining safe coal mining. Investigating their mechanisms and influential factors is crucial to preventing and controlling such disasters in tunneling roadways of extra-thick coal seams.
