[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] like Figure 1-3 As shown, a ground subsidence monitoring device for coal mining areas includes a main body 1, on which a fixing seat 2, a sleeve 3 and an early warning seat 4 are arranged, the fixing seat 2 is integrally formed and symmetrically connected to the middle of both sides of the main body 1, a through hole 5 is opened in the middle of the top of the fixing seat 2, the sleeve 3 is integrally formed and symmetrically connected to both ends of the main body 1, the early warning seat 4 is fixed to the middle of the top of the main body 1 by screws, a docking thread 6 is opened on the inner top of the sleeve 3, a sealing cover 7 is threadedly connected to the docking thread 6, a storage bin 8 is opened inside the early warning seat 4, the bottom of the storage bin 8 is connected to the sleeve 3 through a wire hole 9, a spring 10 is placed above the sleeve 3, a gravity shaft rod 11 is placed at the bottom of the spring 10, a pull-wire switch 12 is symmetrically installed and fixed at the front and rear ends of the storage bin 8 by screws, the top of the pull-wire switch 12 is connected to an alarm module 13 through a wire, the pull-wire switch 12 is electrically connected to a power supply through a wire, and a pull wire 14 on the pull-wire switch 12 passes through the wire hole 9 and is fixedly connected to the symmetrical gravity shaft rod 11.

[0017] Specific usage: the main body 1 is installed and fixed on the ground through the expansion screw and the through hole 5, and the sleeve 3 is nested in the ground; when the ground collapses, the bottom of the sleeve 3 loses its supporting force, and the gravity shaft 11 moves downward along the sleeve 3 under the push of the spring 10. The gravity shaft 11 moves downward to pull the pull wire 14. After the pull wire 14 is subjected to the tension, the pull wire switch 12 is turned on. After the pull wire switch 12 is turned on, the alarm module 13 is activated to perform an alarm operation.

[0018] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
