Embodiment Construction
[0032] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings, but the present invention is not limited thereto.
[0033] refer to Figure 1 to Figure 8
[0034] A support method for the caving zone and broken zone of a metal underground mine roadway, comprising the following steps:
[0035] 1) According to the length of the falling area or the broken zone 1, install the support rail 2 on both sides of the ground in the roadway in advance. In order to consider the problem of equipment transportation, the length of the rail is designed to be 1-1.5m, and the rails can be extended by bolts; and Install the first arch support 10 that is provided with the inverted U-shaped track 11 along its outline in the safe area at one end of the roadway;
[0036] 2) According to the length of the falling area or the broken zone, guide rods...

The invention relates to a roadway collapsed zone and crushed zone supporting method for a metallic underground mine. Support rails are mounted on two ground sides of a roadway, and a first arch support is mounted as well; guide rods are mounted on two sides of the first arch support respectively according to the length of a collapsed zone or a crushed zone; prefabricated second to nth arch supports are mounted on the support rails respectively and moved to appointed positions through a driving mechanism respectively; supporting plates are mounted on inverted U-shaped rails of the first to nth arch supports sequentially; grouting pipes penetrating the collapsed zone or the crushed zone are mounted at intervals on the supporting plates, and arch rods extending into a rock layer above the collapsed zone or the crushed zone are penetratingly arranged in the grouting pipes; the collapsed zone or the crushed zone is grouted, and supporting of the collapsed zone or the crushed zone is finished after hardening of mortar. The problem of supporting of the roadway collapsed zone and the crushed zone of the metallic underground mine is solved, and high safety and construction efficiency are achieved.
Description
technical field [0001] The invention relates to a supporting method for the caving area and the broken zone of the metal underground mine roadway. Background technique [0002] At present, for the support of the caving area and broken zone of the non-coal underground mine roadway, when the roadway caving occurs, the usual measures are to use steel arch frame and concrete support, and the caving area uses the grouting method to fill the goaf , or fill the caving area with sleepers. When the roadway construction encounters the broken zone, it usually uses mortar bolts or grouting to pass through the broken zone. Regardless of the construction plan, during the construction process, workers and equipment are often exposed to dangerous areas. Secondary falls may occur in the fall area at any time, and stones may fall from the broken zone at any time, which may cause casualties or equipment damage in severe cases. damage. Moreover, in the supporting process, the degree of mechan...
