Dynamic response of surrounding rock of gob roadway when the seismic focus height is 50 m.
(a) Horizontal variation of roadway floor and roof stress
(b) Displacement of roof, floor, and two sides of roadway
(c) Displacement speed of roadway roof and floor and two sides
(d) Displacement acceleration of roadway roof and floor and two sides
