Zusammenfassung: | The utility model belongs to the technical field of underground coal mine construction equipment, and particularly relates to a temporary support device for underground coal mine rock drift tunneling, which comprises four steel plates, two connecting rods, two I-beams, a plurality of resin anchor rods, a wood plate, four hanging rings and the like. The two I-shaped steel beams penetrate through the center of the hanging ring in the direction of the roadway and extend to the moraine head section, and wood plates are laid on the I-shaped steel beams extending to the moraine head section. The device has the beneficial effects that after the device is put into use, an anchor rod supporting section is not constructed before an operator constructs an anchor rod supporting top plate and a moraine head section is tunneled, and the operation is not performed under an empty roof, so that the personal safety of the operator is ensured to a great extent; the device is easy to install, the required materials are common ma |
