description The utility model discloses a mine single hydraulic prop pressing device which comprises a test platform frame, the test platform frame is composed of two pieces of top channel steel, two pieces of first connecting transverse steel, two pieces of bottom channel steel and a plurality of pieces of second connecting transverse steel, and the two pieces of first connecting transverse steel are welded between the two ends of the opposite sides of the two pieces of top channel steel. The second connecting transverse steel is welded between the opposite sides of the two bottom steel channels at equal intervals, the connecting vertical steel distributed at equal intervals is welded between the bottom of the top steel channel and the top of the bottom steel channel, and the total number of the connecting vertical steel is two times that of the second connecting transverse steel. Whether the single column leaks liquid or not and whether the value of the pressure gauge changes or not can be observed, whether the single
