Supporting mechanism applied to coal wall caving experiment and experiment device thereof

The utility model relates to the technical field of stope coal wall caving indoor experiments, in particular to a supporting mechanism applied to a coal wall caving experiment and an experimental device and a supporting mechanism thereof, which comprise a groove structure and a support arm structure, the groove structure is arranged in the middle of the base, and a plurality of transverse inserting grooves are formed in the groove structure at intervals in the extending direction of the groove structure. The supporting arm structure is arranged at the bottom of the bearing table, and the lowerend of the supporting arm structure can be inserted into the transverse inserting groove. When the bearing table is loaded in an inclined state, the bottom of the bearing table can be supported in anauxiliary mode through the supporting mechanism, and the overall structure is more stable. The supporting mechanism is simple in design and high in practicability. 本实用新型涉及采场煤壁片帮室内实验技术领域，尤其是涉及一种应用于煤壁片帮实验的支撑机构及其实验装置，支撑机构，其包括：凹槽
