Embodiment approach

[0026] Such as figure 2 As shown, the present invention adopts the method of separate support of the anchor cable 5 and the anchor rod 7 to support the roadway roof, the anchor cable 5 cooperates with the T140 steel belt 3 for support, and the anchor rod 7 cooperates with the trapezoidal steel beam 6 for support. Concrete device and implementation method are as follows:

[0027] Anchor cable 5 and anchor rod 7 are separated, anchor cable 5 cooperates with T140 steel belt 3 for support, and anchor rod 7 cooperates with trapezoidal steel beam 6 for support, including the following steps:

[0028] Step 1, before the excavation construction, place the T140 steel belt 3 and trapezoidal steel beam 6 used for roof support in parallel with the beam 1 of the advanced temporary support device on the longitudinal beam 2 of the advanced temporary support device, according to the center line of the roadway, the specified Adjust the position of the T140 steel belt 3 and the trapezoidal st...

Abstract

The invention discloses a roadway roof support device and support method. A roadway support mode is changed, and a top support mode is changed from anchor rod and anchor cable support in cooperation with a T140 steel belt to anchor rod and anchor cable separation support. By adopting an advance and temporary support device as a support, the time of manually contacting the steel belt in the whole process is short, the procedure of ascending operation is omitted, the risk coefficient of artificially installing the steel belt is effectively reduced, the construction speed is increased, the operation method is simple, the manpower is saved, the support density is increased without adding the purchase process of extra tools and raw materials, and the roadway roof support device and support method are suitable for popularization.

Description

technical field [0001] The invention belongs to the field of roadway support, and in particular relates to a roadway roof support device and a support method. Background technique [0002] In order to strengthen the support strength of the 416 auxiliary roadway, Huangling Mining No. 2 Coal Mine changed the roadway support method, and the top support method changed from anchor rod and anchor cable with seven-hole T140 steel belt support to anchor rod and anchor cable Separate support, in the support change design, the T140 steel belt is only used for anchor cables. Since there is no anchor cable in the advanced temporary support device, the T140 steel belt can only be installed manually after the advanced temporary support device. [0003] The difficulty of manual installation of T140 steel belt lies in the fact that the height of the roadway is 3.8m, and the personnel need to go up the ladder or the frame board. Two people cooperate to penetrate the steel belt hole into the ...
