Abstract

The invention discloses a detection method, a device and a data processing device of a coal gangue pollution scope. The detection method comprises obtaining satellite remote sensing data in an object region; drawing plant spectral information data in the satellite remote sensing data; and determining the coal gangue pollution scope in the object region according to the plant spectral information data. By means of the detection method, the device and the data processing device, detection of the coal gangue pollution scope can be convenient and fast.

Description

technical field [0001] The invention relates to the field of surveying, in particular to a method and device for detecting coal gangue pollution range and data processing equipment. Background technique [0002] Coal gangue is the solid waste discharged during the coal mining and washing process, mainly including rocks in the coal seam and roof and floor rocks, and its quantity accounts for about 15% of the raw coal output. In the past half a century, due to the massive mining of coal fields, a large area of ​​coal gangue stockpiles has been formed near the coal mines. The existence of gangue dumps not only occupies a large amount of land, but also a large amount of sulfides (mainly pyrite) contained in the strata where they are located will flow into the surrounding environment when encountering continuous rainfall or heavy rain, causing pollution. At the same time, it also promotes the oxidation reaction of pyrite, resulting in high concentrations of metal ions such as ir...
