Zusammenfassung: | The invention relates to the technical field of coal mine safety, in particular to a coal mine roof and floor sandstone water yield analysis and detection device. The coal mine roof and floor sandstone water-abundance analysis and detection device provided by the invention can integrate drilling and water sampling, can rapidly analyze and detect the sandstone water-abundance, and is relatively convenient and rapid to operate. A coal mine roof and floor sandstone water yield analysis and detection device comprises a base, side frames, a middle column, a turning frame and the like, the side frames are connected to the upper sides of the left portion and the right portion of the base, the middle column is rotationally connected between the upper portions of the side frames, and the turning frame is connected to the middle column. The middle column is rotated after drilling is completed through the drill bit, the middle column rotates to drive the turning frame and the auxiliary frame to rotate, the outer barrel |
