Beschreibung
Zusammenfassung:	The utility model relates to the technical field of mine ground pressure monitoring, and discloses a coal mine mine ground pressure monitoring device which comprises a bottom supporting plate, a threaded rod is movably sleeved outside the bottom supporting plate, a threaded sleeve is in threaded connection outside the threaded rod, and a limiting plate is movably sleeved outside the top end of the threaded sleeve. And the inner side of the limiting plate is movably sleeved with a positioning sleeve, a pressure detector is installed on the inner side of the positioning sleeve, and the outer portion of the threaded sleeve is fixedly connected with a limiting plate. According to the coal mine ground pressure monitoring device, a helical gear is continuously pushed to move downwards through a spring, that is, the helical gear and a second helical gear are kept in a meshing motion state, meanwhile, a rotating rod is rotated, the rotating rod can carry the helical gear to rotate, the helical gear drives a threaded
