Abstract: Disclosed is an angle-adjustable three-dimensional physical simulation device for equivalent coal seam mining, which comprises a base, a frame, a loading frame, an angle-adjusting device, a limiting plate and a lifting combined module. The top of the base is fixedly connected with the frame; the top of the frame is fixedly connected with the loading frame; the angle-adjusting device is located between the base and the frame; the bottom of the frame is fixedly connected with the limiting plate; the limiting plate is penetrated with a lifting combined module; the lifting combined module comprises a plurality of lifting pieces, and the lifting pieces comprise bolts and cushion blocks; the bolt penetrates through the limiting plate and is in threaded connection with the limiting plate; and one end in the bolt frame is rotatably connected with the cushion block.
