Abstract

The invention belongs to the technical field of coal mining, and particularly relates to a coal bunker support and a construction process thereof. The coal bunker support comprises a coal bunker and a support, wherein the coal bunker comprises a coal bunker cover plate, a coal bunker body, a coal bunker hopper and a loading chamber, wherein the coal bunker cover plate is arranged at the top of the coal bunker body, the coal bunker hopper is arranged at the bottom of the coal bunker body, the loading chamber is arranged below the coal bunker body, the coal bunker body is provided with an anchor net spraying support, the coal bunker hopper is provided with a track support, and the loading chamber is provided with an anchor net spraying and metal shed support. The construction process comprises the following steps of (1), performing coal bunker body construction; (2), performing coal bunker funnel construction; (3), performing loading chamber construction; and (4), performing coal bunker cover plate construction. According to the construction process, the support cost is reduced, operation is easy, the construction period is greatly shortened, the obtained coal bunker support is good in use effect, the bunker body strength, the coal bunker funnel section strength, the loading chamber deformation and other aspects can meet the safety production requirement, the strength is greatly improved, and the service life of the support is met.

Description

technical field [0001] The invention belongs to the technical field of coal mine mining, and in particular relates to a coal bunker support and a construction process thereof. Background technique [0002] With the continuous development of the coal industry and the continuous improvement of coal mining efficiency, in order to ensure safe and efficient production, it is essential to have a safe and strong underground coal bunker. In order to prevent the pressure of the surrounding rocks from causing damage to the coal bunker structure, generally A support is provided to reinforce the warehouse body. The choice of coal bunker support is not only related to the support strength of the coal bunker itself, but also has an important impact on the future working face. In the construction of large coal bunkers, the use of reasonable support methods plays a positive role in promoting safe production, reducing labor intensity and economic benefits. [0003] The traditional coal bun...
