[0001] The invention relates to the technical field of coal mining operations, in particular to a rapid cooling device for a hydraulic support used for coal mining. Background Art

[0002] Hydraulic support is a structure used to control the mine pressure of coal mining working face. The mine pressure of the mining face acts on the hydraulic support in the form of external load. In the mechanical system of interaction between the hydraulic support and the surrounding rock of the mining face, if the combined force of each support of the hydraulic support and the combined force of the external load acting on the hydraulic support by the roof are exactly in the same straight line, then the hydraulic support is very suitable for the surrounding rock of the mining face.
