This research aims to understand the deformation behavior of roadways in extra-thick coal seams and to propose effective control methods.
Conducted on-site measurements and theoretical calculations to analyze surrounding rock deformation.
Simulated the stress transfer characteristics during excavation and mining phases.
Developed and implemented a zonal differentiated support scheme for roadway control.
Identified that roadway deformation becomes asymmetric, with more pronounced subsidence at the ribs and roof.
Observed a shift in the stress concentration zone towards the mining face at 7 m ahead.
Field tests confirmed that the proposed support scheme met the safe production standards for the mine.
