Fracture Mechanical Behavior of Cracked Cantilever Roof with Large Cutting Height Mining
Accurately predicting the roof collapse span is crucial in ensuring the safe production of thick seam mining with large mining height, which is easy in forming a “cantilever beam” structure. Considering roof damage caused by roadway excavation and coal seam mining disturbance, the fracture mechanics...
