With the continuous increase of coal mining intensity, higher requirements have been put forward for the supporting performance of hydraulic support. The hydraulic support always has a dynamic coupling state with the surrounding rock. Investigating its dynamic adaptation characteristics to surrounding rock is of great significance for improving the support performance of hydraulic supports. Therefore, the numerical analysis model of the “hydraulic support-surrounding rock” coupling system is established by taking ZZ 17000 / 33 / 72 D hydraulic support in Kouzidong Coal Mine as an example and using explicit dynamic analysis software Ls-dyna. The dynamic bearing characteristics and pressure distribution law of the four-column hydraulic support-surrounding rock coupling system under different mining heights and different bearing conditions are analyzed. Moreover, key vulnerable connection units and the four-column hydraulic support in-stability under full load conditions are clarified.
