Response and control technology for entry loaded by mining abutment stress of a thick hard roof

- The evolution of abutment stress has been obtained by borehole stress monitoring.
- The short-term strong abutment stress has been classified as four stress signals.
- The strong response for the entry has been revealed.
- The influence of the main roof fracture position on the entry has been discussed.
- The hydraulic fracturing has been recommended to control the main roof fracture.
