A Novel Index to Detect Opencast Coal Mine Areas From ...
These surface mining areas can be detected through satellite images using this cue. It has been found in this paper, that the spectral index derived from SWIR-I (1.566-1.651 μm) and SWIR-II (2.107-2.294 μm) bands of Landsat 8 exhibit distinctive features to detect high mineral areas of …

Land-use mapping and change detection in a coal mining ...
Abstract In an area like the Jharia coalfield (JCF), where extensive and rapid underground and opencast mining is going on continuously, land-use studies are of paramount importance. This paper discusses the remote sensing-GIS techniques used for identification of various land-use classes on satellite imagery and enhanced products and identification of time-sequential changes in land-use patterns.

Appalachian Surface Coal Mining Delineation – Andrew Pericak
Surface coal mines are big and easy to spot by looking at satellite imagery. While a previous dataset had mapped surface mining, it only depicted mines at a decadal interval from 1975 through 2005 and was not peer-reviewed. My dataset addressed these limitations by creating an annual dataset and providing open, peer-reviewed methods—and by ...
