Embodiment 1
[0050]This embodiment discloses a method for quickly obtaining the estimated parameters of mining subsidence in mining areas by using UAV technology. The main steps are as follows: Establish a UAV surface mobile observation station within the mining area → use UAVs to conduct multi-phase mining subsidence Dynamic monitoring, completion of field data collection → internal data processing of field data obtained by drones, each period of monitoring data generates a corresponding mine surface DEM (Digital Elevation Model, digital elevation model), and multi-period monitoring data formation Multi-period DEM of the subsidence area, get the surface subsidence value of the mining area by subtracting the multi-period DEM → use the probability integral dynamic prediction model to invert to obtain the estimated surface subsidence parameters → use the inversion obtained surface subsidence estimated parameters for the mining area and surrounding areas Prediction of subsidence in the mining ...
Embodiment 2
[0082] This embodiment discloses a method for quickly obtaining the predicted parameters of mining subsidence in a mining area by using unmanned aerial vehicle technology, which is applied to the Wangjiata Coal Mine in Inner Mongolia.
[0083] Overview of the research area: Wangjiata Coal Mine 2S201 working face is located in Ordos City, Inner Mongolia Autonomous Province. The working face has a strike length of about 1253m, a dip length of about 260m, an average coal seam inclination of 2°, a mining depth of about 200m, and an average mining thickness of 3.26m, see the table below for specific parameters.
[0084]
[0085] The boundary angle is used to draw the mining influence range of the 2S201 working face, and the boundary angle is 45°, and the control point layout position of the influence boundary image is obtained. Since the range is smaller this time, the flight range covers the entire area of influence.
