COALCoal and Openpit surface mining impacts on American Lands (COAL) COAL is a Python library for processing hyperspectral imagery from remote sensing devices such as the Airborne Visible/InfraRed Imaging Spectrometer (AVIRIS). COAL provides a suite of algorithms for classifying land cover, identifying mines and other geographic features, and correlating them with environmental data sets.
Mining | National Geographic SocietyMining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times. Prehistoric people first mined flint, which was ideal for tools and weapons since it breaks into shards with sharp edges.

The Mining Process | Earth Resources Observation and ...Lands disturbed by coal mining must be restored to a condition that can support the uses it could support before mining (or even make the land better). In the closeup images, the mined land seems to move over time. As the mining and beginnings of the reclamation process take place, we can see the digging and backfilling occurring. (See the animations in the subsection called "Animations" to ...
