Coal and Open-pit 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.

· The main form of mining in the Elk Valley is open-pit surface mining. Open-pit surface mining involves the removal of rock from the surface to form large, open pits (Banglam, Ataei, & Sayadi, 2012). Rock that is removed from the open pits, referred to as waste rock, overburden, or spoil, is moved to nearby piles or adjacent

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
Open-pit mining or opencast mining refers to a method of extracting rock or minerals from the earth by their removal from an open pit or borrow. It is a form of surface mining. The term is used to differentiate this form of mining from extractive methods that require tunneling into the earth, like longwall mining.. Open-pit mines are used when deposits of minerals or rock are found near the ...

This is a type of surface mining that involves the extraction of minerals and other materials ...
Coal mining was initiated at the study site in 1969, and has been ongoing for 31 of the past 35 years, using both underground room and pillar and open pit truck and shovel operations. The surface operations began in 1972. The current operator has been mining on the property since 2004. Open pit geometry is based on highwalls (pit slopes
Open-pit Mining Operations. Open-pit mines are dug on benches that are between four and sixty-meters in size, depending on the size of machinery used to excavate. The walls of most open-pit mines are dug at an angle and include steps to prevent avalanches from occurring inside the build site.
Two types of mining techniques are used: Open-pit mining and underground mining. Open-pit mining includes blasting of soil and vegetation to access underground ore layers or coal seams  nsequently, this method produces large volumes of mining waste, including soil and overburden, which increase the vulnerability of mining environments to soil erosion and pollution.

· 1. Introduction. The slope angle, mining boundary, changes of the coal seam thickness, etc. are the main reasons that many coal resources remain under the end-walls in open-pit coal mines [1–3] cause of the undeveloped mining technology and low economic benefits, those resources were discarded or exploited using the room and pillar method with low recovery ratios.
