Abstract

The invention discloses a method and a device for detecting a subsidence area of ground and data processing equipment. The method for detecting the subsidence area of ground comprises the following steps: acquiring satellite remote sensing image data in a target area; extracting plant spectral information data in the satellite remote sensing image data; judging whether an area matched with the plant spectral information data in a reference area exists in the target area or not, wherein the reference area refers to an area with the known subsidence condition of ground; and determining the subsidence condition of ground in a first area to be identical to that in the reference area when the first area in the target area is matched with the plant spectral information data in the reference area. According to the invention, the detection result is objective and accurate.

Description

technical field [0001] The invention relates to the field of surveying, in particular to a detection method and device for a ground subsidence area and data processing equipment. Background technique [0002] Ground subsidence is one of the main hidden dangers of underground coal mining. At the same time, geological disasters such as ground fissures, landslides and debris flows caused by ground subsidence will also bring huge losses. Under the background of global warming and frequent extreme weather, After the heavy rain in the mining area, it is easy to cause sudden geological disasters. In the existing technology, it mainly relies on long-term accumulated production experience, such as coal seam mining thickness, mining time, and driving direction, to predict the ground subsidence situation. This method exists There are many subjective factors and low accuracy, so it is difficult to objectively determine and early warning ground subsidence, so that corresponding preventio...
