Embodiment Construction
[0022] In order to make the above-mentioned features and advantages of the present invention more obvious and easy to understand, the following specific embodiments are given and the accompanying drawings are described in detail as follows, but the present invention is not limited thereto.
[0023] refer to Figure 1 to Figure 8
[0024] A device for supporting the caving area and crushing zone 1 of metal underground mine roadway, including a plurality of arch supports 10 for being installed under the caving area or crushing zone of underground mine roadway and arranged at intervals along the longitudinal direction. The support is carried from the safe area of the roadway to the safe area at the other end of the roadway across the caving area or broken. The two sides of the arched support are respectively provided with guiding and stabilizing mechanisms 40 for the installation of the arched support. The arched support is provided with arched rails 20 along its outline. The...

The invention relates to a device used for supporting of a metal underground mine roadway collapsed zone and crushed zone. The device comprises a plurality of arch supports installed under the metal underground mine roadway collapsed zone or crushed zone at intervals in the longitudinal direction. Guide stabilization mechanisms are arranged on two sides of the arch supports. The arch supports are provided with arch rails correspondingly along the outlines. Arch supporting plates formed by splicing a plurality of formworks are arranged in the arch rails, and the arch supporting plates on every two adjacent arch supports are connected end to end. A traction mechanism used during formwork installation is further arranged on one side of the arch supports. The device is compact in structure, realizes supporting in the metal underground mine roadway collapsed zone and crushed zone, and is high in safety and construction efficiency.
Description
technical field [0001] The invention relates to a device for supporting the caving area and the crushing zone of the metal underground mine roadway. Background technique [0002] At present, for the support of the caving area and the broken zone of the non-coal underground mine roadway, when the roadway caving, the usual measures are to use steel arches and concrete support, and use the grouting method to fill the goaf in the caving area. , or fill the caving area with sleepers. When the roadway construction encounters the broken zone, the mortar bolt is usually used, or the grouting method is used to pass the broken zone. No matter what kind of construction plan, in the process of construction, workers and equipment are often exposed to dangerous areas, secondary caving will occur at any time in the caving area, and stones will fall at any time in the crushing zone, which may cause casualties or equipment in serious cases. of damage. And in the support process, the degree...
