Claim 14:
15. A monitoring method for dynamic development of an overburden mining separated bed, used for monitoring dynamic development of a separated bed using the monitoring device of claim 1,
comprising the steps of:
S1, determining a mounting depth of the settlement magnetic ring assembly based on a range of a separated bed development region;
S2, probing information of a rock stratum in a mounting depth range of the settlement magnetic ring assembly, and determining a mounting position and a number of the settlement magnetic ring assembly;
S3, determining a time of the monitoring hole starting to drill based on information of coal mining footage of a working face and a drilling rate of the monitoring hole, and completing construction of the monitoring hole; and
S4, mounting the settlement magnetic ring assembly at a position with a preset depth in the monitoring hole, using a layered settlement monitoring system to monitor the dynamic development of the separated bed, and obtaining a rock stratum settlement amount and a separated bed development height.
