Abstract: Based on the analysis of the structure of hydraulic supports, this paper analyzed the common safety failures and preventive
measures of underground hydraulic supports in coal mines separately, hoping to provide guarantee for the safer and more
efficient use of underground hydraulic supports.

Key words: hydraulic support; safety failure; preventive measures
