Study on the Method of Pressure Relief and Energy Absorption for Protecting Roadway Under Thick and Hard Roof

Thick and hard roofs are frequently encountered geological conditions during coal mining operations. In such conditions, the deformation of the surrounding rock in roadways due to dynamic pressure disturbances has become a prominent factor that hinders the safe and efficient production of coal mines...
