A kind of support for mine concrete support engineering and its support method

Abstract

The present application relates to a support for mine concrete support engineering and its support method, which comprises a plurality of first support plates and two second support plates respectively located on both sides of the first support plate. The bottom is provided with a first support portion, the bottom of the second support plate is provided with a second support portion, a connecting portion is provided between the first support portion and the two second support plates, and the connecting portion includes a first connecting rod, a second A connecting rod and a connecting sleeve, one end of the first connecting rod is hinged with the first support part, the other end is inserted in the connecting sleeve and is threadedly connected with the connecting sleeve, one end of the second connecting rod is hinged with the second supporting plate, and the other end is inserted into the connecting sleeve. It is arranged at one end of the connecting sleeve away from the first connecting rod, and is threadedly connected with the connecting sleeve, and the threads on the first connecting rod and the second connecting rod are in opposite directions. The present application has the effect of enabling the bracket to support mine caves of different shapes and sizes, and avoiding fixing between the bracket and the inner wall of the mine cave.

Description

technical field [0001] The present application relates to the field of mine support engineering, in particular to a support for mine concrete support engineering and a support method thereof. Background technique [0002] With the rapid development of my country's economy, the demand for mineral resources is increasing year by year. At present, in mine production, in order to prevent the mining face from collapsing, ensure the safety of mining, and improve the efficiency of mining, it is necessary to carry out effective support during the mining process to eliminate hidden safety hazards in mine production and meet the actual needs of mine production. . [0003] The existing support methods for the excavation face in the mine cave mainly include masonry support, shed type support and bolt support, among which the shed type support is the most commonly used form of support in mine cave support. The common supporting structure generally uses several arched brackets to suppor...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that the existing support is a structure with a certain shape and size, which cannot support mines of different shapes and sizes; and the support needs to be fixed to the inner wall of the mine. When the inner wall of the mine cave partially collapses, it will affect the installation stability of the bracket
