Description

Technical Field

[0001] The utility model relates to the technical field of tunnel support, in particular to a shielding type hydraulic support structure. Background Art

[0002] Hydraulic supports are structures used to control mine pressure in coal mining faces. Mining pressure acts on the hydraulic supports in the form of external loads. In the mechanical system of the interaction between the hydraulic supports and the surrounding rock mass, if the combined force of the hydraulic support's supporting components is aligned with the combined external load acting on the hydraulic support from the roof, the hydraulic support is well adapted to the surrounding rock mass. In a fully-mechanized, single-stage, fully-mechanized mining face, the hydraulic supports, shearer, and front conveyor collectively perform roof support, coal cutting, loading, and transportation. The base is the primary support and load-bearing component of the support and serves as the foundation for the entire support.

[0003] The space for coal mining in underground coal mines is small and the ventilation effect is poor. A large amount of dust is generated during the working face mining operation and hydraulic support adjustment process. This dust not only affects the health of workers but also poses a major hidden danger to production safety. Therefore, dust suppression equipment is needed to improve the working face environment.
