  • Monitoring device and method for dynamic development of overburden mining separated bed
    Patent number: 11879336
    Abstract: A monitoring device and a monitoring method for dynamic development of an overburden mining separated bed are provided. The monitoring device includes a settlement magnetic ring assembly and a mounting conduit. The settlement magnetic ring assembly includes an anchor strap assembly, a magnetic induction iron ring and a magnetic ring sleeve sleeved outside the magnetic induction iron ring. The anchor strap assembly is arranged at the outer circumference of the magnetic ring sleeve and has a contraction state and an expansion state. The anchor strap assembly in the contraction state can move in a monitoring hole, and at least two fixing points at different heights are formed in the anchor strap assembly in the expansion state and the wall of the monitoring hole in a vertical direction. Two ends of the mounting conduit are connected to a drill rod and the magnetic ring sleeve respectively.
