COAL AND OPEN-PIT SURFACE MINING NASA

2017-11-2  COAL AND OPEN-PIT SURFACE MINING IMPACTS ON AMERICAN LANDS (COAL) COAL is a Python library for processing hyperspectral imagery from the Airborne Visible/InfraRed Imaging Spectrometer (AVIRIS-C & AVIRIS-NG) Mineral Classification. • All minerals have unique spectral signatures. • Samples of those spectral signatures are contained in spectral

Coal Mines an overview ScienceDirect Topics

Fischer (1957) reported results from coal-dust explosion experiments in a 260-m long experimental coal-mine gallery of equivalent-circle cross-sectional diameter of 3.2 m, ie, L/D of about 80. The main purpose of these experiments was to investigate whether deposits of stone dust on shelves in the upper part of the gallery cross section would prevent the propagation of coal-dust explosions in the gallery.

Other prominent features include a coal hauling road that runs between the active mine site and a coal slurry impoundment at the top right part of the scene. These impoundments contain the coal slurry (sludge) left over from washing the coal. Since the 2002 image was captured, the western section of the mine has continued to expand.

Classification of fires in coal waste dumps based on

2020-11-11  A self-heating intensity index (SHII) based on the highest (pixel max.) and lowest (pixel min.) values taken from satellite thermal maps of burning coal waste dumps are proposed. The index enables the classification of such fires in Ukrainian- and Polish coal waste dumps. Both in Ukraine and in Poland, varying thermal intensities during 1985–2019 are revealed, using the SHII and following
