Abstract: Hydraulic support is an important mechanical equipment in the coal mine. In order to avoid liquid leakage and fluid
channeling and ensure the safety and stability of coal mining process, this paper discussed the liquid leakage of hydraulic support
and its solutions. It briefly introduced the internal structure of the hydraulic support cylinder, analyzed the common liquid leakage
phenomenon and the causes, and put forward the corresponding solutions.

Key words: hydraulic support; liquid leakage; maintenance; sealing element
