Combined component for supporting coal mine tunnel

The utility model relates to the technical field of roadway supporting, and discloses a combined component for supporting a coal mine roadway. The number of the supporting pipes is two, the two supporting pipes are oppositely and longitudinally arranged on the two sides in a roadway, and longitudinal strip-shaped holes are formed in the opposite sides of the two supporting pipes. The lifting component comprises a carrier plate and a lifting assembly, the carrier plate is slidably connected into the supporting pipe, and the lifting assembly is arranged at the bottom of the carrier plate; the lifting assembly is used for driving the carrier plate to ascend and descend. The buffer assembly is arranged on the carrying plate, the two ends of the arch-shaped frame penetrate through the strip-shaped holes of the two supporting pipes to be arranged on the buffer assembly, by means of the combined component for roadway supporting, roadway deformation can be transferred when ground pressure appears, a supporting body i
